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.

حَدَّثَنَا يَعْلَى حَدَّثَنَا الْأَعْمَشُ عَنْ عَبْدِ اللَّهِ بْنِ مُرَّةَ عَنْ مَسْرُوقٍ عَنْ عَبْدِ اللَّهِ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ لَا يَحِلُّ دَمُ رَجُلٍ يَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنِّي رَسُولُ اللَّهِ إِلَّا أَحَدَ ثَلَاثَةِ نَفَرٍ النَّفْسُ بِالنَّفْسِ وَالثَّيِّبُ الزَّانِي وَالتَّارِكُ لِدِينِهِ الْمُفَارِقُ لِلْجَمَاعَةِ
