[AI] It was narrated that the Messenger of Allah ﷺ said: "The blood of a Muslim who testifies that there is no god but Allah and that Muhammad is the Messenger of Allah, is not lawful to shed, except in one of three cases: a married person who commits adultery, a life for a life, or one who forsakes his religion and separates from the community."

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَا يَحِلُّ دَمُ امْرِئٍ مِنْ أَهْلِ الْقِبْلَةِ إِلَّا بِإِحْدَى ثَلَاثٍ قَتَلَ فَيُقْتَلَ وَالثَّيِّبُ الزَّانِي وَالْمُفَارِقُ لِلْجَمَاعَةِ أَوْ قَالَ «الْخَارِجُ مِنَ الْجَمَاعَةِ»

[AI] She said that the blood of anyone from the people of the Qibla is not permissible except in three cases: a (murderer) should be killed in retaliation, and an adulterous married person (the punishment for whom is stoning to death), and the deserter from the Muslim community.

أَنَّهَا قَالَتْ لَا يَحِلُّ دَمُ أَحَدٍ مِنْ أَهْلِ الْقِبْلَةِ إِلَّا بِإِحْدَى ثَلَاثٍ رَجُلٌ قَتَلَ فَيُقْتَلَ بِهِ وَالثَّيِّبُ الزَّانِي وَالْمُفَارِقُ لِلْجَمَاعَةِ

The blood of a Muslim man who testifies that there is no god but Allah and that I am the Messenger of Allah should not be lawfully shed but only for one of three reasons: married fornicator, soul for soul, and one who deserts his religion separating himself from the community. (Using translation from Abū Dāʾūd 4352)

قَالَ رَسُولُ اللَّهِ ﷺ «لَا يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ يَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنِّي رَسُولُ اللَّهِ إِلَّا بِإِحْدَى ثَلَاثٍ الثَّيِّبُ الزَّانِي وَالنَّفْسُ بِالنَّفْسِ وَالتَّارِكُ لِدِينِهِ الْمُفَارِقُ الْجَمَاعَةَ»
