"The Messenger of Allah [SAW] said: 'By the One besides Whom there is no other god, it is not permissible to shed the blood of a Muslim who bears witness to La ilaha illalla (there is none worthy of worship except Allah) and that I am the Messenger of Allah, except in three cases: One who leaves Islam and splits away from the Jama'ah, a person who has been married and then commits adultery, and a life for a life.'"  

قَالَ رَسُولُ اللَّهِ ﷺ وَالَّذِي لاَ إِلَهَ غَيْرُهُ لاَ يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ يَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنِّي رَسُولُ اللَّهِ إِلاَّ ثَلاَثَةُ نَفَرٍ التَّارِكُ لِلإِسْلاَمِ مُفَارِقُ الْجَمَاعَةِ وَالثَّيِّبُ الزَّانِي وَالنَّفْسُ بِالنَّفْسِ قَالَ الأَعْمَشُ فَحَدَّثْتُ بِهِ إِبْرَاهِيمَ فَحَدَّثَنِي عَنِ الأَسْوَدِ عَنْ عَائِشَةَ بِمِثْلِهِ  

"Aishah said: 'Do you not know that the Messenger of Allah [SAW] said: It is not permissible to shed the blood of a Muslim, except a man who committed adultery after being married, or one who reverted to Kufr after becoming Muslim, or a life for a life.'"  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ إِلاَّ رَجُلٌ زَنَى بَعْدَ إِحْصَانِهِ أَوْ كَفَرَ بَعْدَ إِسْلاَمِهِ أَوِ النَّفْسُ بِالنَّفْسِ وَقَّفَهُ زُهَيْرٌ  

"Aishah said: 'O 'Ammar! Do you not know that it is not permissible to shed the blood of a Muslim except in three cases: a life for a life, a man who commits adultery after being married.'"  

عَائِشَةُ يَا عَمَّارُ أَمَا إِنَّكَ تَعْلَمُ أَنَّهُ لاَ يَحِلُّ دَمُ امْرِئٍ إِلاَّ ثَلاَثَةٌ النَّفْسُ بِالنَّفْسِ أَوْ رَجُلٌ زَنَى بَعْدَ مَا أُحْصِنَ وَسَاقَ الْحَدِيثَ  

"We were with 'Uthman when he was under siege and we could hear what was said from Al-Balat. 'Uthman came in one day, then he came out, and said: 'They are threatening to kill me.' We said: 'Allah will suffice you against them.' He said: 'Why would they kill me? I heard the Messenger of Allah [SAW] say: It is not permissible to shed the blood of a Muslim except in one of three cases: A man who reverts to Kufr after becoming Muslim, or commits adultery after being married, or one who kills a soul unlawfully. By Allah, I did not commit adultery during Jahiliyyah or in Islam, I never wished to follow any other religion since Allah guided me, and I have never killed anyone, so why do they want to kill me?'"  

نَسْمَعُ كَلاَمَ مَنْ بِالْبَلاَطِ فَدَخَلَ عُثْمَانُ يَوْمًا ثُمَّ خَرَجَ فَقَالَ إِنَّهُمْ لَيَتَوَاعَدُونِي بِالْقَتْلِ قُلْنَا يَكْفِيكَهُمُ اللَّهُ قَالَ فَلِمَ يَقْتُلُونِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ إِلاَّ بِإِحْدَى ثَلاَثٍ رَجُلٌ كَفَرَ بَعْدَ إِسْلاَمِهِ أَوْ زَنَى بَعْدَ إِحْصَانِهِ أَوْ قَتَلَ نَفْسًا بِغَيْرِ نَفْسٍ فَوَاللَّهِ مَا زَنَيْتُ فِي جَاهِلِيَّةٍ وَلاَ إِسْلاَمٍ وَلاَ تَمَنَّيْتُ أَنَّ لِي بِدِينِي بَدَلاً مُنْذُ هَدَانِي اللَّهُ وَلاَ قَتَلْتُ نَفْسًا فَلِمَ يَقْتُلُونَنِي
