The Messenger of Allah [SAW] said: "Whoever unsheathes his sword and starts to strike the people with it, it is permissible to shed his blood."  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ مَنْ شَهَرَ سَيْفَهُ ثُمَّ وَضَعَهُ فَدَمُهُ هَدَرٌ  

'Abdur-Razzaq narrated a similar report with the same chain, but he did not attribute it to the Prophet [SAW]  

أَنْبَأَنَا عَبْدُ الرَّزَّاقِ بِهَذَا الإِسْنَادِ مِثْلَهُ وَلَمْ يَرْفَعْهُ  

"Whoever wields a weapon and starts to strike (the people) with it, it is permissible to shed his blood."  

مَنْ رَفَعَ السِّلاَحَ ثُمَّ وَضَعَهُ فَدَمُهُ هَدَرٌ  

The Prophet [SAW] said: "Whoever bears weapons against us, he is not one of us."  

أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ حَمَلَ عَلَيْنَا السِّلاَحَ فَلَيْسَ مِنَّا  

"When 'Ali was in Yemen, he sent some gold that was still enclosed in rock to the Prophet [SAW], who distributed it among Al-Aqra' bin Habis Al-Hanzali, who belonged to Banu Mujashi', 'Uyaynah bin Badr Al-Fazari, 'Alqamah bin 'Ulathah Al-'Amiri, who belonged to Banu Kilab and Zaid Al-Khail At-Ta'I, who belonged to Banu Nabhan. The Quraish and the Ansar became angry and said: 'He gives to the chiefs of Najd and ignores us!' He said: 'I am seeking to win them over (firmly to Islam).' Then a man with sunken eyes, a bulging forehead, a thick beard and a shaven head came and said: 'O Muhammad, fear Allah!' He said: 'Who will obey Allah if I do not? He trusts me with the people of this Earth but you do not trust me.' A man among the people asked for permission to kill him, but he did not let him do that. When (the man) went away, he (the Prophet [SAW]) said: 'Among the offspring of this man there will be people who will recite the Qur'an but it will not go beyond their throats, and they will go out of Islam as an arrow goes through the target. They will kill the Muslims and leave the idol-worshippers alone. If I live to see them, I will kill them as the killing of 'Ad.'"  

بَعَثَ عَلِيٌّ إِلَى النَّبِيِّ ﷺ وَهُوَ بِالْيَمَنِ بِذُهَيْبَةٍ فِي تُرْبَتِهَا فَقَسَمَهَا بَيْنَ الأَقْرَعِ بْنِ حَابِسٍ الْحَنْظَلِيِّ ثُمَّ أَحَدِ بَنِي مُجَاشِعٍ وَبَيْنَ عُيَيْنَةَ بْنِ بَدْرٍ الْفَزَارِيِّ وَبَيْنَ عَلْقَمَةَ بْنِ عُلاَثَةَ الْعَامِرِيِّ ثُمَّ أَحَدِ بَنِي كِلاَبٍ وَبَيْنَ زَيْدِ الْخَيْلِ الطَّائِيِّ ثُمَّ أَحَدَ بَنِي نَبْهَانَ قَالَ فَغَضِبَتْ قُرَيْشٌ وَالأَنْصَارُ وَقَالُوا يُعْطِي صَنَادِيدَ أَهْلِ نَجْدٍ وَيَدَعُنَا فَقَالَ إِنَّمَا أَتَأَلَّفُهُمْ فَأَقْبَلَ رَجُلٌ غَائِرَ الْعَيْنَيْنِ نَاتِئَ الْوَجْنَتَيْنِ كَثَّ اللِّحْيَةِ مَحْلُوقَ الرَّأْسِ فَقَالَ يَا مُحَمَّدُ اتَّقِ اللَّهَ قَالَ مَنْ يُطِعِ اللَّهَ إِذَا عَصَيْتُهُ أَيَأْمَنُنِي عَلَى أَهْلِ الأَرْضِ وَلاَ تَأْمَنُونِي فَسَأَلَ رَجُلٌ مِنَ الْقَوْمِ قَتْلَهُ فَمَنَعَهُ فَلَمَّا وَلَّى قَالَ إِنَّ مِنْ ضِئْضِئِ هَذَا قَوْمًا يَخْرُجُونَ يَقْرَءُونَ الْقُرْآنَ لاَ يُجَاوِزُ حَنَاجِرَهُمْ يَمْرُقُونَ مِنَ الدِّينِ مُرُوقَ السَّهْمِ مِنَ الرَّمِيَّةِ يَقْتُلُونَ أَهْلَ الإِسْلاَمِ وَيَدَعُونَ أَهْلَ الأَوْثَانِ لَئِنْ أَنَا أَدْرَكْتُهُمْ لأَقْتُلَنَّهُمْ قَتْلَ عَادٍ  

"I heard the Messenger of Allah [SAW] say: 'At the end of time there will appear young people with foolish minds. Their faith will not pass through their throats, and they will go out of Islam as an arrow goes through the target. If you meet them, then kill them, for killing them will bring reward to the one who killed them on the Day of Resurrection.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ يَخْرُجُ قَوْمٌ فِي آخِرِ الزَّمَانِ أَحْدَاثُ الأَسْنَانِ سُفَهَاءُ الأَحْلاَمِ يَقُولُونَ مِنْ خَيْرِ قَوْلِ الْبَرِيَّةِ لاَ يُجَاوِزُ إِيمَانُهُمْ حَنَاجِرَهُمْ يَمْرُقُونَ مِنَ الدِّينِ كَمَا يَمْرُقُ السَّهْمُ مِنَ الرَّمِيَّةِ فَإِذَا لَقِيتُمُوهُمْ فَاقْتُلُوهُمْ فَإِنَّ قَتْلَهُمْ أَجْرٌ لِمَنْ قَتَلَهُمْ يَوْمَ الْقِيَامَةِ  

"I used to wish that I could meet a man among the Companions of the Prophet [SAW] and ask him about the Khawarij. Then I met Abu Barzah on the day of 'Id, with a number of his companions. I said to him: 'Did you hear the Messenger of Allah [SAW] mention the Khawarij?' He said: 'Yes. I heard the Messenger of Allah [SAW] with my own ears, and saw him with my own eyes. Some wealth was brought to the Messenger of Allah [SAW] and he distributed it to those on his right and on his left, but he did not give anything to those who were behind him. Then a man stood behind him and said: "O Muhammad! You have not been just in your division!" He was a man with black patchy (shaved) hair, wearing two white garments. So Messenger of Allah [SAW] became very angry and said: "By Allah! You will not find a man after me who is more just than me." Then he said: "A people will come at the end of time; as if he is one of them, reciting the Qur'an without it passing beyond their throats. They will go through Islam just as the arrow goes through the target. Their distinction will be shaving. They will not cease to appear until the last of them comes with Al-Masih Ad-Dajjal. So when you meet them, then kill them, they are the worst of created beings."  

أَنْ أَلْقَى رَجُلاً مِنْ أَصْحَابِ النَّبِيِّ ﷺ أَسْأَلُهُ عَنِ الْخَوَارِجِ فَلَقِيتُ أَبَا بَرْزَةَ فِي يَوْمِ عِيدٍ فِي نَفَرٍ مِنْ أَصْحَابِهِ فَقُلْتُ لَهُ هَلْ سَمِعْتَ رَسُولَ اللَّهِ ﷺ يَذْكُرُ الْخَوَارِجَ فَقَالَ نَعَمْ سَمِعْتُ رَسُولَ اللَّهِ ﷺ بِأُذُنِي وَرَأَيْتُهُ بِعَيْنِي أُتِيَ رَسُولُ اللَّهِ ﷺ بِمَالٍ فَقَسَمَهُ فَأَعْطَى مَنْ عَنْ يَمِينِهِ وَمَنْ عَنْ شِمَالِهِ وَلَمْ يُعْطِ مَنْ وَرَاءَهُ شَيْئًا فَقَامَ رَجُلٌ مِنْ وَرَائِهِ فَقَالَ يَا مُحَمَّدُ مَا عَدَلْتَ فِي الْقِسْمَةِ رَجُلٌ أَسْوَدُ مَطْمُومُ الشَّعْرِ عَلَيْهِ ثَوْبَانِ أَبْيَضَانِ فَغَضِبَ رَسُولُ اللَّهِ ﷺ غَضَبًا شَدِيدًا وَقَالَ وَاللَّهِ لاَ تَجِدُونَ بَعْدِي رَجُلاً هُوَ أَعْدَلُ مِنِّي ثُمَّ قَالَ يَخْرُجُ فِي آخِرِ الزَّمَانِ قَوْمٌ كَأَنَّ هَذَا مِنْهُمْ يَقْرَءُونَ الْقُرْآنَ لاَ يُجَاوِزُ تَرَاقِيَهُمْ يَمْرُقُونَ مِنَ الإِسْلاَمِ كَمَا يَمْرُقُ السَّهْمُ مِنَ الرَّمِيَّةِ سِيمَاهُمُ التَّحْلِيقُ لاَ يَزَالُونَ يَخْرُجُونَ حَتَّى يَخْرُجَ آخِرُهُمْ مَعَ الْمَسِيحِ الدَّجَّالِ فَإِذَا لَقِيتُمُوهُمْ فَاقْتُلُوهُمْ هُمْ شَرُّ الْخَلْقِ وَالْخَلِيقَةِ قَالَ أَبُو عَبْدِ الرَّحْمَنِ رَحِمَهُ اللَّهُ شَرِيكُ بْنُ شِهَابٍ لَيْسَ بِذَلِكَ الْمَشْهُورِ
