Abu Hurairah reported the Apostle of Allaah ﷺ as saying “ I am commanded to fight with men till they testify that there is no god but Allaah, when they do that they will keep their life and property safe from me, except what is due to them. (i.e., life and property) and their reckoning will be at Allaah’s hands.”  

قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لاَ إِلَهَ إِلاَّ اللَّهُ فَإِذَا قَالُوهَا مَنَعُوا مِنِّي دِمَاءَهُمْ وَأَمْوَالَهُمْ إِلاَّ بِحَقِّهَا وَحِسَابُهُمْ عَلَى اللَّهِ تَعَالَى  

The Prophet ﷺ said: I am commanded to fight with men till they testify that there is no god but Allah, and that Muhammad is His servant and His Apostle, face our qiblah (direction of prayer), eat what we slaughter, and pray like us. When they do that, their life and property are unlawful for us except what is due to them. They will have the same rights as the Muslims have, and have the same responsibilities as the Muslims have.  

قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَشْهَدُوا أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ وَأَنْ يَسْتَقْبِلُوا قِبْلَتَنَا وَأَنْ يَأْكُلُوا ذَبِيحَتَنَا وَأَنْ يُصَلُّوا صَلاَتَنَا فَإِذَا فَعَلُوا ذَلِكَ حَرُمَتْ عَلَيْنَا دِمَاؤُهُمْ وَأَمْوَالُهُمْ إِلاَّ بِحَقِّهَا لَهُمْ مَا لِلْمُسْلِمِينَ وَعَلَيْهِمْ مَا عَلَى الْمُسْلِمِينَ  

Anas bin Malik reported the Apostle of Allaah ﷺ as saying “ I am commanded to fight with the polytheists. The rest of the tradition is to the same effect as mentioned above.”  

قَالَ رَسُولُ اللَّهِ ﷺ أُمِرْتُ أَنْ أُقَاتِلَ الْمُشْرِكِينَ بِمَعْنَاهُ  

Usamah bin Zaid said “The Messenger of Allah ﷺ sent us with a detachment to Al Huruqat. They learnt about us and fled away. But we found a man, when we attacked him he uttered “There is no god but Allaah, still we struck him till we killed him.” When I mentioned it to the Prophet ﷺ he said “Who will save you from “There is no god but Allaah” on the Day of Judgment? I said “Messenger of Allah ﷺ, he uttered it for the fear of the weapon.” He said “Did you tear his heart so that you learnt whether he actually uttered it for this or not. Who will support you against “There is no god but Allaah”? He kept on repeating this till I wished I would have embraced Islam on that day.  

بَعَثَنَا رَسُولُ اللَّهِ ﷺ سَرِيَّةً إِلَى الْحُرَقَاتِ فَنَذِرُوا بِنَا فَهَرَبُوا فَأَدْرَكْنَا رَجُلاً فَلَمَّا غَشَيْنَاهُ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ فَضَرَبْنَاهُ حَتَّى قَتَلْنَاهُ فَذَكَرْتُهُ لِلنَّبِيِّ ﷺ فَقَالَ مَنْ لَكَ بِلاَ إِلَهَ إِلاَّ اللَّهُ يَوْمَ الْقِيَامَةِ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّمَا قَالَهَا مَخَافَةَ السِّلاَحِ قَالَ أَفَلاَ شَقَقْتَ عَنْ قَلْبِهِ حَتَّى تَعْلَمَ مِنْ أَجْلِ ذَلِكَ قَالَهَا أَمْ لاَ مَنْ لَكَ بِلاَ إِلَهَ إِلاَّ اللَّهُ يَوْمَ الْقِيَامَةِ فَمَا زَالَ يَقُولُهَا حَتَّى وَدِدْتُ أَنِّي لَمْ أُسْلِمْ إِلاَّ يَوْمَئِذٍ  

Al Miqdad bin Al Aswad reported that he said “Apostle of Allaah ﷺ tell me if I meet a man who is a disbeliever and he fights with me and cuts off one hand of mine with the sword and then takes refuge by a tree and says “I embraced Islam for Allah’s sake. Should I kill him, Apostle of Allaah ﷺ after he uttered it (the credo of Islam)? The Apostle of Allaah ﷺ said “Do not kill him”. I said “Apostle of Allaah ﷺ, he cut off my hand. The Apostle of Allaah ﷺ said, Do not kill him. I f you kill him, he will become like you before you kill him and you will become like him before he uttered his credo which he has uttered now.  

أَنَّهُ أَخْبَرَهُ أَنَّهُ قَالَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ إِنْ لَقِيتُ رَجُلاً مِنَ الْكُفَّارِ فَقَاتَلَنِي فَضَرَبَ إِحْدَى يَدَىَّ بِالسَّيْفِ ثُمَّ لاَذَ مِنِّي بِشَجَرَةٍ فَقَالَ أَسْلَمْتُ لِلَّهِ أَفَأَقْتُلُهُ يَا رَسُولَ اللَّهِ بَعْدَ أَنْ قَالَهَا قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَقْتُلْهُ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّهُ قَطَعَ يَدِي قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَقْتُلْهُ فَإِنْ قَتَلْتَهُ فَإِنَّهُ بِمَنْزِلَتِكَ قَبْلَ أَنْ تَقْتُلَهُ وَأَنْتَ بِمَنْزِلَتِهِ قَبْلَ أَنْ يَقُولَ كَلِمَتَهُ الَّتِي قَالَ
