When Messenger of Allah ﷺ died and Abu Bakr became the caliph some Arabs renegade (reverted to disbelief) (Abu Bakr decided to declare war against them), ʿUmar, said to Abu Bakr, "How can you fight with these people although Messenger of Allah ﷺ said, 'I have been ordered (by Allah) to fight the people till they say: "None has the right to be worshipped but Allah, and whoever said it then he will save his life and property from me except on trespassing the law (rights and conditions for which he will be punished justly), and his accounts will be with Allah.' " Abu Bakr said, "By Allah! I will fight those who differentiate between the prayer and the Zakat as Zakat is the compulsory right to be taken from the property (according to Allah's orders) By Allah! If they refuse to pay me even a she-kid which they used to pay at the time of Messenger of Allah ﷺ . I would fight with them for withholding it" Then ʿUmar said, "By Allah, it was nothing, but Allah opened Abu Bakr's chest towards the decision (to fight) and I came to know that his decision was right."  

لَمَّا تُوُفِّيَ رَسُولُ اللَّهِ ﷺ وَكَانَ أَبُو بَكْرٍ ؓ وَكَفَرَ مَنْ كَفَرَ مِنَ الْعَرَبِ فَقَالَ عُمَرُ ؓ كَيْفَ تُقَاتِلُ النَّاسَ وَقَدْ قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ فَمَنْ قَالَهَا فَقَدْ عَصَمَ مِنِّي مَالَهُ وَنَفْسَهُ إِلاَّ بِحَقِّهِ وَحِسَابُهُ عَلَى اللَّهِ فَقَالَ وَاللَّهِ لأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الصَّلاَةِ وَالزَّكَاةِ فَإِنَّ الزَّكَاةَ حَقُّ الْمَالِ وَاللَّهِ لَوْ مَنَعُونِي عَنَاقًا كَانُوا يُؤَدُّونَهَا إِلَى رَسُولِ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَى مَنْعِهَا قَالَ عُمَرُ ؓ فَوَاللَّهِ مَا هُوَ إِلاَّ أَنْ قَدْ شَرَحَ اللَّهُ صَدْرَ أَبِي بَكْرٍ ؓ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

Abu Bakr said, "By Allah! If they (pay me the Zakat and) withhold even a young (female) goat which they used to pay during the lifetime of Messenger of Allah ﷺ, I will fight with them for it." ʿUmar said, "It was nothing but Allah Who opened Abu Bakr's chest towards the decision to fight, and I came to know that his decision was right."  

أَبُو بَكْرٍ ؓ وَاللَّهِ لَوْ مَنَعُونِي عَنَاقًا كَانُوا يُؤَدُّونَهَا إِلَى رَسُولِ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَى مَنْعِهَا قَالَ عُمَرُ ؓ فَمَا هُوَ إِلاَّ أَنْ رَأَيْتُ أَنَّ اللَّهَ شَرَحَ صَدْرَ أَبِي بَكْرٍ ؓ بِالْقِتَالِ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

When the Prophet ﷺ died and Abu Bakr became his successor and some of the Arabs reverted to disbelief, ʿUmar said, "O Abu Bakr! How can you fight these people although Messenger of Allah ﷺ said, 'I have been ordered to fight the people till they say: 'None has the right to be worshipped but Allah, 'and whoever said, 'None has the right to be worshipped but Allah', Allah will save his property and his life from me, unless (he does something for which he receives legal punishment) justly, and his account will be with Allah?' "Abu Bakr said, "By Allah! I will fight whoever differentiates between prayers and Zakat as Zakat is the right to be taken from property (according to Allah's Orders). By Allah! If they refused to pay me even a kid they used to pay to Messenger of Allah ﷺ, I would fight with them for withholding it." ʿUmar said, "By Allah: It was nothing, but I noticed that Allah opened Abu Bakr's chest towards the decision to fight, therefore I realized that his decision was right."  

لَمَّا تُوُفِّيَ النَّبِيُّ ﷺ وَاسْتُخْلِفَ أَبُو بَكْرٍ وَكَفَرَ مَنْ كَفَرَ مِنَ الْعَرَبِ قَالَ عُمَرُ يَا أَبَا بَكْرٍ كَيْفَ تُقَاتِلُ النَّاسَ وَقَدْ قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ فَمَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ عَصَمَ مِنِّي مَالَهُ وَنَفْسَهُ إِلاَّ بِحَقِّهِ وَحِسَابُهُ عَلَى اللَّهِ قَالَ أَبُو بَكْرٍ وَاللَّهِ لأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الصَّلاَةِ وَالزَّكَاةِ فَإِنَّ الزَّكَاةَ حَقُّ الْمَالِ وَاللَّهِ لَوْ مَنَعُونِي عَنَاقًا كَانُوا يُؤَدُّونَهَا إِلَى رَسُولِ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَى مَنْعِهَا قَالَ عُمَرُ فَوَاللَّهِ مَا هُوَ إِلاَّ أَنْ رَأَيْتُ أَنْ قَدْ شَرَحَ اللَّهُ صَدْرَ أَبِي بَكْرٍ لِلْقِتَالِ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

When Messenger of Allah ﷺ died and Abu Bakr was elected as a Caliph after him, some of the Arabs reverted to disbelief, ʿUmar said to Abu Bakr, "How dare you fight the people while Messenger of Allah ﷺ said, I have been ordered to fight the people till they say 'None has the right to be worshipped but Allah' And whoever says: None has the right to be worshipped but Allah.' waves his wealth and his life from me unless he deserves a legal punishment lusty, and his account will be with Allah! Abu Bakr said, "By Allah, I will fight him who discriminates between Zakat and prayers, for Zakat is the Compulsory right to be taken from the wealth By Allah, if they refuse to give me even a tying rope which they use to give to Messenger of Allah ﷺ, I would fight them for withholding it." ʿUmar said, 'By Allah, It was nothing, except I saw that Allah had opened the chest of Abu Bakr to the fight, and I came to know for certain that was the truth."  

لَمَّا تُوُفِّيَ رَسُولُ اللَّهِ ﷺ وَاسْتُخْلِفَ أَبُو بَكْرٍ بَعْدَهُ وَكَفَرَ مَنْ كَفَرَ مِنَ الْعَرَبِ قَالَ عُمَرُ لأَبِي بَكْرٍ كَيْفَ تُقَاتِلُ النَّاسَ وَقَدْ قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ فَمَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ عَصَمَ مِنِّي مَالَهُ وَنَفْسَهُ إِلاَّ بِحَقِّهِ وَحِسَابُهُ عَلَى اللَّهِ فَقَالَ وَاللَّهِ لأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الصَّلاَةِ وَالزَّكَاةِ فَإِنَّ الزَّكَاةَ حَقُّ الْمَالِ وَاللَّهِ لَوْ مَنَعُونِي عِقَالاً كَانُوا يُؤَدُّونَهُ إِلَى رَسُولِ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَى مَنْعِهِ فَقَالَ عُمَرُ فَوَاللَّهِ مَا هُوَ إِلاَّ أَنْ رَأَيْتُ اللَّهَ قَدْ شَرَحَ صَدْرَ أَبِي بَكْرٍ لِلْقِتَالِ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

Why would you fight against the people, when the Messenger of Allah declared: I have been directed to fight against people so long as they do not say: There is no god but Allah, and he who professed it was granted full protection of his property and life on my behalf except for a right? His (other) affairs rest with Allah. Upon this Abu Bakr said: By Allah, I would definitely fight against him who severed prayer from Zakat, for it is the obligation upon the rich. By Allah, I would fight against them even to secure the cord (used for hobbling the feet of a camel) which they used to give to the Messenger of Allah (as zakat) but now they have withheld it. Umar b. Khattab remarked: By Allah, I found nothing but the fact that Allah had opened the heart of Abu Bakr for (perceiving the justification of) fighting (against those who refused to pay Zakat) and I fully recognized that the (stand of Abu Bakr) was right.  

لَمَّا تُوُفِّيَ رَسُولُ اللَّهِ ﷺ وَاسْتُخْلِفَ أَبُو بَكْرٍ بَعْدَهُ وَكَفَرَ مَنْ كَفَرَ مِنَ الْعَرَبِ قَالَ عُمَرُ بْنُ الْخَطَّابِ لأَبِي بَكْرٍ كَيْفَ تُقَاتِلُ النَّاسَ وَقَدْ قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ فَمَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ فَقَدْ عَصَمَ مِنِّي مَالَهُ وَنَفْسَهُ إِلاَّ بِحَقِّهِ وَحِسَابُهُ عَلَى اللَّهِ فَقَالَ أَبُو بَكْرٍ وَاللَّهِ لأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الصَّلاَةِ وَالزَّكَاةِ فَإِنَّ الزَّكَاةَ حَقُّ الْمَالِ وَاللَّهِ لَوْ مَنَعُونِي عِقَالاً كَانُوا يُؤَدُّونَهُ إِلَى رَسُولِ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَى مَنْعِهِ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ فَوَاللَّهِ مَا هُوَ إِلاَّ أَنْ رَأَيْتُ اللَّهَ ﷻ قَدْ شَرَحَ صَدْرَ أَبِي بَكْرٍ لِلْقِتَالِ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

"When the Messenger of Allah [SAW] died, the 'Arabs apostatized, so 'Umar said: 'O Abu Bakr, how can you fight the 'Arabs?' Abu Bakr said: 'The Messenger of Allah [SAW] said: "I have been commanded to fight the people until they bear witness to La ilaha illallah (there is none worthy of worship except Allah) and that I am the Messenger of Allah, and they establish Salah and pay Zakah." By Allah, if they withhold from me a young goat that they used to give to the Messenger of Allah [SAW], I will fight them for it.' 'Umar said: 'By Allah, as soon as I realized how certain Abu Bakr was, I knew that it was the truth.'"  

لَمَّا تُوُفِّيَ رَسُولُ اللَّهِ ﷺ ارْتَدَّتِ الْعَرَبُ فَقَالَ عُمَرُ يَا أَبَا بَكْرٍ كَيْفَ تُقَاتِلُ الْعَرَبَ فَقَالَ أَبُو بَكْرٍ إِنَّمَا قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَشْهَدُوا أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنِّي رَسُولُ اللَّهِ وَيُقِيمُوا الصَّلاَةَ وَيُؤْتُوا الزَّكَاةَ وَاللَّهِ لَوْ مَنَعُونِي عَنَاقًا مِمَّا كَانُوا يُعْطُونَ رَسُولَ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَيْهِ قَالَ عُمَرُ فَلَمَّا رَأَيْتُ رَأْىَ أَبِي بَكْرٍ قَدْ شُرِحَ عَلِمْتُ أَنَّهُ الْحَقُّ  

"When the Messenger of Allah [SAW] died and Abu Bakr became the Khalifah after him, and some of the 'Arabs reverted to Kufr, 'Umar said to Abu Bakr: 'How can you fight the people when the Messenger of Allah [SAW] said: I have been commanded to fight the people until they say La ilaha illallah (there is none worthy of worship but Allah). Whoever says La ilaha illallah, his wealth and his life are safe from me except for a right that is due, and his reckoning will be with Allah.?' Abu Bakr said: 'By Allah, I will fight whoever separates Salah and Zakah, for Zakah is the compulsory right to be taken from wealth. By Allah, if they withhold from me a rope that they used to give to the Messenger of Allah [SAW], I will fight them for withholding it.' 'Umar, may Allah be pleased with him, said: 'By Allah, as soon as I realized that Allah has expanded the chest of Abu Bakr for fighting, I knew that it was the truth.'"  

لَمَّا تُوُفِّيَ رَسُولُ اللَّهِ ﷺ وَاسْتُخْلِفَ أَبُو بَكْرٍ وَكَفَرَ مَنْ كَفَرَ مِنَ الْعَرَبِ قَالَ عُمَرُ لأَبِي بَكْرٍ كَيْفَ تُقَاتِلُ النَّاسَ وَقَدْ قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ فَمَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ عَصَمَ مِنِّي مَالَهُ وَنَفْسَهُ إِلاَّ بِحَقِّهِ وَحِسَابُهُ عَلَى اللَّهِ قَالَ أَبُو بَكْرٍ وَاللَّهِ لأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الصَّلاَةِ وَالزَّكَاةِ فَإِنَّ الزَّكَاةَ حَقُّ الْمَالِ وَاللَّهِ لَوْ مَنَعُونِي عِقَالاً كَانُوا يُؤَدُّونَهُ إِلَى رَسُولِ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَى مَنْعِهِ قَالَ عُمَرُ فَوَاللَّهِ مَا هُوَ إِلاَّ أَنِّي رَأَيْتُ اللَّهَ شَرَحَ صَدْرَ أَبِي بَكْرٍ لِلْقِتَالِ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

"The Messenger of Allah [SAW] said: 'I have been commanded to fight the people until they say La ilaha illallah. If they say it then their blood and their wealth are safe from me, except for a right that is due, and their reckoning will be with Allah.' When the people apostatized, 'Umar said to Abu Bakr: 'Will you fight them when you heard the Messenger of Allah [SAW] say such and such?' He said: 'By Allah, I do not separate Salah and Zakah, and I will fight whoever separates them.' So we fought alongside him, and we realized that that was the right thing."  

قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ فَإِذَا قَالُوهَا فَقَدْ عَصَمُوا مِنِّي دِمَاءَهُمْ وَأَمْوَالَهُمْ إِلاَّ بِحَقِّهَا وَحِسَابُهُمْ عَلَى اللَّهِ فَلَمَّا كَانَتِ الرِّدَّةُ قَالَ عُمَرُ لأَبِي بَكْرٍ أَتُقَاتِلُهُمْ وَقَدْ سَمِعْتَ رَسُولَ اللَّهِ ﷺ يَقُولُ كَذَا وَكَذَا فَقَالَ وَاللَّهِ لاَ أُفَرِّقُ بَيْنَ الصَّلاَةِ وَالزَّكَاةِ وَلأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَهُمَا فَقَاتَلْنَا مَعَهُ فَرَأَيْنَا ذَلِكَ رُشْدًا قَالَ أَبُو عَبْدِ الرَّحْمَنِ سُفْيَانُ فِي الزُّهْرِيِّ لَيْسَ بِالْقَوِيِّ وَهُوَ سُفْيَانُ بْنُ حُسَيْنٍ

Abu Bakr said: 'I will fight whoever separates Salah and Zakah, for Zakah is the compulsory right to be taken from wealth.

عُمَرُ يَا أَبَا بَكْرٍ كَيْفَ تُقَاتِلُ النَّاسَ وَقَدْ قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ فَإِذَا قَالُوهَا عَصَمُوا مِنِّي دِمَاءَهُمْ وَأَمْوَالَهُمْ إِلاَّ بِحَقِّهَا قَالَ أَبُو بَكْرٍ ؓ لأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الصَّلاَةِ وَالزَّكَاةِ وَاللَّهِ لَوْ مَنَعُونِي عَنَاقًا كَانُوا يُؤَدُّونَهَا إِلَى رَسُولِ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَى مَنْعِهَا قَالَ عُمَرُ ؓ فَوَاللَّهِ مَا هُوَ إِلاَّ أَنْ رَأَيْتُ أَنَّ اللَّهَ تَعَالَى قَدْ شَرَحَ صَدْرَ أَبِي بَكْرٍ لِقِتَالِهِمْ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

"When the Messenger of Allah died, and Abu Bakr became the Khalifah after him, and some of the 'Arabs reverted to disbelief. 'umar said to Abu Bakr: 'How can you fight the people when the Messenger of allah said: "I have been commanded to fight the people until they say La ilaha illallah (there is none worthy of worship but Allah). Whoever says La ilaha illah, his wealth and his life safe from me, unless he deserves a legal punishment justly, and his reckoning will be with Allah?"' Abu Bakr, may Allah be pleased with him, said: 'I will fight anyone who separates prayer and Zakah; Zakah is the compulsory right to be taken from wealth. By Allah, if they withhold from me a rope that they used to give to the Messenger of Allah, I will fight them for wiholding it.' 'Umar, may Allah be pleased with him, said: 'By Allah, it was as if I saw that Allah has opened the heart of Abu Bakr for fighting, and I knew that I was the truth."'  

لَمَّا تُوُفِّيَ رَسُولُ اللَّهِ ﷺ وَاسْتُخْلِفَ أَبُو بَكْرٍ بَعْدَهُ وَكَفَرَ مَنْ كَفَرَ مِنَ الْعَرَبِ قَالَ عُمَرُ لأَبِي بَكْرٍ كَيْفَ تُقَاتِلُ النَّاسَ وَقَدْ قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ فَمَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ عَصَمَ مِنِّي مَالَهُ وَنَفْسَهُ إِلاَّ بِحَقِّهِ وَحِسَابُهُ عَلَى اللَّهِ فَقَالَ أَبُو بَكْرٍ ؓ لأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الصَّلاَةِ وَالزَّكَاةِ فَإِنَّ الزَّكَاةَ حَقُّ الْمَالِ وَاللَّهِ لَوْ مَنَعُونِي عِقَالاً كَانُوا يُؤَدُّونَهُ إِلَى رَسُولِ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَى مَنْعِهِ قَالَ عُمَرُ ؓ فَوَاللَّهِ مَا هُوَ إِلاَّ أَنْ رَأَيْتُ اللَّهَ شَرَحَ صَدْرَ أَبِي بَكْرٍ لِلْقِتَالِ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

Abu Hurairah said When the Messenger of Allah ﷺ died and Abu Bakr was made his successor after him and certain Arab clans apostatized. Umar bin Al Khattab said to Abu Bakr How can you fight with the people until they say “There is no God but Allah” so whoever says “There is no God but Allah”, he has protected his property and his person from me except for what is due from him, and his reckoning is left to allah. Abu Bak replied I swear by Allah that I will certainly fight with those who make a distinction between prayer and zakat, for zakat is what is due from property. I swear by Allah that if they were to refuse me a rope of camel (or a female kid, according to another version)which they used to pay the Messenger of Allah, I will fight with them over the refusal of it. Umar bin Al Khattab said I swear by Allah, I clearly saw Allah had made Abu Bakr feel justified in tighting and I recognized that it was right. Abu Dawud said This tradition has been transmitted by Rabah bin Zaid from Ma’mar and Al Zaubaidi from Al Zuhri has “If they were to refuse me a female kid.” The version transmitted by ‘Anbasah from Yunus on the authority of Al Zuhri has “a female kid”.  

لَمَّا تُوُفِّيَ رَسُولُ اللَّهِ ﷺ وَاسْتُخْلِفَ أَبُو بَكْرٍ بَعْدَهُ وَكَفَرَ مَنْ كَفَرَ مِنَ الْعَرَبِ قَالَ عُمَرُ بْنُ الْخَطَّابِ لأَبِي بَكْرٍ كَيْفَ تُقَاتِلُ النَّاسَ وَقَدْ قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ فَمَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ عَصَمَ مِنِّي مَالَهُ وَنَفْسَهُ إِلاَّ بِحَقِّهِ وَحِسَابُهُ عَلَى اللَّهِ ﷻ فَقَالَ أَبُو بَكْرٍ وَاللَّهِ لأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الصَّلاَةِ وَالزَّكَاةِ فَإِنَّ الزَّكَاةَ حَقُّ الْمَالِ وَاللَّهِ لَوْ مَنَعُونِي عِقَالاً كَانُوا يُؤَدُّونَهُ إِلَى رَسُولِ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَى مَنْعِهِ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ فَوَاللَّهِ مَا هُوَ إِلاَّ أَنْ رَأَيْتُ اللَّهَ ﷻ قَدْ شَرَحَ صَدْرَ أَبِي بَكْرٍ لِلْقِتَالِ قَالَ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

said: "When the Messenger of Allah ﷺ died and Abu Bakr became the Khalifah after him, whoever disbelieved from the Arabs disbelieved, so Umar bin Al-Khattab said to Abu Bakr: 'How will you fight the people while the Messenger of Allah has said: 'I have been ordered to fight the people until they say La Ilaha Illallah, and if they say that, then their blood and wealth will be protected from me, except what it makes obligatory upon them, and their reckoning is with Allah?' So Abu Bakr said: 'By Allah I will fight whoever differentiates between Salat and Zakat. For indeed, Zakat is the right due upon wealth. And by Allah! If they withhold even (camel) tethers which they used to give to the Messenger of Allah ﷺ I will fight them for withholding it.' So Umar bin Al-Khattab said: 'By Allah! I saw that Allah had opened Abu Bakr's chest to fighting, so I knew that it was correct.'"  

لَمَّا تُوُفِّيَ رَسُولُ اللَّهِ ﷺ وَاسْتُخْلِفَ أَبُو بَكْرٍ بَعْدَهُ كَفَرَ مَنْ كَفَرَ مِنَ الْعَرَبِ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ لأَبِي بَكْرٍ كَيْفَ تُقَاتِلُ النَّاسَ وَقَدْ قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ وَمَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ عَصَمَ مِنِّي مَالَهُ وَنَفْسَهُ إِلاَّ بِحَقِّهِ وَحِسَابُهُ عَلَى اللَّهِ قَالَ أَبُو بَكْرٍ وَاللَّهِ لأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الزَّكَاةِ وَالصَّلاَةِ فَإِنَّ الزَّكَاةَ حَقُّ الْمَالِ وَاللَّهِ لَوْ مَنَعُونِي عِقَالاً كَانُوا يُؤَدُّونَهُ إِلَى رَسُولِ اللَّهِ ﷺ لَقَاتَلْتُهُمْ عَلَى مَنْعِهِ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ فَوَاللَّهِ مَا هُوَ إِلاَّ أَنْ رَأَيْتُ أَنَّ اللَّهَ قَدْ شَرَحَ صَدْرَ أَبِي بَكْرٍ لِلْقِتَالِ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

When the Messenger of Allah ﷺ died and some people apostatised, ‘Umar bin al-Khattab said: O Abu Bakr, how can you fight the people, when the Messenger of Allah ﷺ said: “I have been commanded to fight the people until they say La ilaha illallah (There is no god but Allah), and whoever says La ilaha illallah, his wealth and his life are protected from me, and his reckoning will be with Allahʿ? Abu Bakr said: I will most certainly fight those who separate prayer and zakah, for zakah is what is due on wealth. By Allah, if they withhold from me a small she-goat that they used to give to the Messenger of Allah ﷺ, I will certainly fight them for withholding it. ʻUmar said: By Allah, as soon as I saw that Allah had opened Abu Bakrʿs heart to the idea of fighting I knew that he was right.  

عَنْ أَبِي هُرَيْرَةَ قَالَلَمَّا تُوُفِّيَ رَسُولُ اللهِ ﷺ وَكَفَرَ مَنْ كَفَرَ قَالَ قَالَ عُمَرُ بْنُ الْخَطَّابِ يَا أَبَا بَكْرٍ كَيْفَ تُقَاتِلُ النَّاسَ وَقَدْ قَالَ رَسُولُ اللهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لَا إِلَهَ إِلَّا اللهُ فَمَنْ قَالَ لَا إِلَهَ إِلَّا اللهُ فَقَدْ عَصَمَ مِنِّي مَالَهُ وَنَفْسَهُ وَحِسَابُهُ عَلَى اللهِ ﷻ ؟ قَالَ أَبُو بَكْرٍ لَأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الصَّلاةِ وَالزَّكَاةِ إِنَّ الزَّكَاةَ حَقُّ الْمَالِ وَاللهِ لَوْ مَنَعُونِي عَنَاقًا كَانُوا يُؤَدُّونَهَا إِلَى رَسُولِ اللهِ ﷺ لَقَاتَلْتُهُمْ عَلَيْهَا فَقَالَ عُمَرُ وَاللهِ مَا هُوَ إِلَّا أَنْ رَأَيْتُ أَنَّ اللهَ قَدْ شَرَحَ صَدْرَ أَبِي بَكْرٍ بِالْقِتَالِ فَعَرَفْتُ أَنَّهُ الْحَقُّ

When the apostates apostatised at the time of Abu Bakr, ‘Umar said: How can you fight the people, O Abu Bakr, when the Messenger of Allah ﷺ said: “I have been commanded to fight the people until they say La ilaha illallah (There is no god but Allah), and whoever says La ilaha illallah, his wealth and his life are protected from me except in cases dictated by Islamic law, and his reckoning will be with Allahʿ?

By Allah, as soon as I saw that Allah had opened Abu Bakrʿs heart to the idea of fighting, I knew that he was right.  

عُمَرُ كَيْفَ تُقَاتِلُ النَّاسَ يَا أَبَا بَكْرٍ وَقَدْ قَالَ رَسُولُ اللهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لَا إِلَهَ إِلَّا اللهُ فَإِذَا قَالُوا لَا إِلَهَ إِلَّا اللهُ فَقَدْ عَصَمُوا مِنِّي دِمَاءَهُمْ وَأَمْوَالَهُمْ إِلَّا بِحَقِّهَا وَحِسَابُهُمْ عَلَى اللهِ ؟ فَقَالَ أَبُو بَكْرٍ وَاللهِ لَأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَ الصَّلَاةِ وَالزَّكَاةِ فَإِنَّ الزَّكَاةَ حَقُّ الْمَالِ وَاللهِ لَوْ مَنَعُونِي عَنَاقًا كَانُوا يُؤَدُّونَهَا إِلَى رَسُولِ اللهِ ﷺ لَقَاتَلْتُهُمْ عَلَيْهَا قَالَ عُمَرُ فَوَاللهِ مَا هُوَ إِلَّا أَنْ رَأَيْتُ أَنَّ اللهَ قَدْ شَرَحَ صَدْرَ أَبِي بَكْرٍ لِلْقِتَالِ فَعَرَفْتُ أَنَّهُ الْحَقُّ  

“I have been commanded to fight the people until they say La ilaha illallah, and if they say it then their blood and wealth are safe from me, except in cases dictated by sharee'ah, and their reckoning is with Allah.” When some people apostatized, ʼUmar said to Abu Bakr: Will you fight them when you heard the Messenger of Allah is say such and such? Abu Bakr said: By Allah, I will not separate prayer and zakah, and I shall certainly fight anyone who separates them. So we fought them alongside him and we realised that that was the right thing to do.  

عَنِ النَّبِيِّ ﷺ قَالَ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لَا إِلَهَ إِلَّا اللهُ فَإِذَا قَالُوهَا عَصَمُوا مِنِّي دِمَاءَهُمْ وَأَمْوَالَهُمْ إِلَّا بِحَقِّهَا وَحِسَابُهُمْ عَلَى اللهِ قَالَ فَلَمَّا كَانَتِ الرِّدَّةُ قَالَ عُمَرُ لِأَبِي بَكْرٍ تُقَاتِلُهُمْ وَقَدْ سَمِعْتَ رَسُولَ اللهِ ﷺ يَقُولُ كَذَا وَكَذَا؟ قَالَ فَقَالَ أَبُو بَكْرٍ وَاللهِ لَا أُفَرِّقُ بَيْنَ الصَّلاةِ وَالزَّكَاةِ وَلَأُقَاتِلَنَّ مَنْ فَرَّقَ بَيْنَهُمَا قَالَ فَقَاتَلْنَا مَعَهُ فَرَأَيْنَا ذَلِكَ رَشَدًا

"So Abu Bakr decided to fight them, then 'Umar said: 'O Abu Bakr, how can you fight the people when the Messenger of Allah [SAW] said: "I have been commanded to fight the people until they say La ilaha illallah, and if they say it, their blood and their wealth will be safe from me except for a right that is due.?'

"When Abu Bakr mobilized to fight them, 'Umar said: 'O Abu Bakr, how can you fight the people when the Messenger of Allah ﷺ said: "I have been commanded to fight the people until they say La ilaha illallah (there is none worthy or worship except Allah). Whoever says La ilaha illallah, his life and his property are safe from me, except for its right, and his reckoning will be with Allah?'" Abu Bakr, may Allah be pleased with me him, said: 'By Allah, I will surely fight those who separate prayer and Zakah, for Zakah is what is due on wealth. By Allah, if they withhold from me a small she-goat that they used to give to the Messenger of Allah ﷺ I will fight them for withholding it.' ('Umar said) 'By Allah, when I realized that Allah, the Most High, had opened the chest of Abu Bakr to fighting them, then I knew that it was the truth.'" (Using translation from Nasāʾī 3093)

“I have been commanded to fight the people until they say La ilaha illallah, and if they say it then their blood and wealth are safe from me, except in cases dictated by sharee'ah, and their reckoning is with Allah.” When some people apostatized, ʼUmar said to Abu Bakr: Will you fight them when you heard the Messenger of Allah is say such and such? Abu Bakr said: By Allah, I will not separate prayer and zakah, and I shall certainly fight anyone who separates them. So we fought them alongside him and we realised that that was the right thing to do. (Using translation from Aḥmad 67)
