[Machine] The Messenger of Allah ﷺ said, "The blood of a Muslim cannot be shed except by three: a person who commits adultery after being married, a person who renounces their faith after embracing Islam, or a person who kills another person unjustly." Zuhair narrated this hadith from Hilal bin Al-Ala, who narrated it from Hussein, who narrated it from Zuhair, who narrated it from Abu Ishaq, who narrated it from Amr bin Ghallab, who said, "Aisha said, 'O Ammar, do you not know that the shedding of a person's blood is not permissible unless for three reasons: a life for a life, or a person who commits adultery after marriage and being chaste."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «لَا يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ إِلَّا رَجُلٌ زَنَى بَعْدَ إِحْصَانِهِ أَوْ كَفَرَ بَعْدَ إِسْلَامِهِ أَوِ النَّفْسُ بِالنَّفْسِ» وَقَفَهُ زُهَيْرٌ 3467 أَخْبَرَنَا هِلَالُ بْنُ الْعَلَاءِ قَالَ حَدَّثَنَا حُسَيْنٌ قَالَ حَدَّثَنَا زُهَيْرٌ قَالَ حَدَّثَنَا أَبُو إِسْحَاقَ عَنْ عَمْرِو بْنِ غَالِبٍ قَالَ قَالَتْ عَائِشَةُ يَا عَمَّارُ أَمَا إِنَّكَ تَعْلَمُ أَنَّهُ لَا يَحِلُّ دَمُ امْرِئٍ إِلَّا ثَلَاثَةٌ نَفْسٌ بِنَفْسٍ أَوْ رَجُلٌ زَنَى بَعْدَمَا أُحْصِنَ
