حَدَّثَنَا أَبُو مُعَاوِيَةَ حَدَّثَنَا الْأَعْمَشُ عَنْ عَبْدِ اللَّهِ بْنِ مُرَّةَ عَنْ مَسْرُوقٍ عَنْ عَبْدِ اللَّهِ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا يَحِلُّ دَمُ امْرِئٍ يَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنِّي رَسُولُ اللَّهِ إِلَّا بِإِحْدَى ثَلَاثٍ الثَّيِّبُ الزَّانِي وَالنَّفْسُ بِالنَّفْسِ وَالتَّارِكُ لِدِينِهِ الْمُفَارِقُ لِلْجَمَاعَةِ
مسند امام احمد بن حنبل · Hadith 4065
It was narrated that 'Abdullah (RA) said: The Messenger of Allah (PBUH) said: "The blood of a Muslim man who bears witness that there is no god but Allah and that I am the Messenger of Allah is not permissible (to be shed) except in one of three cases: a married adulterer, a soul for a soul, and one who leaves his religion and separates from the jama' ah (the main body of Muslims)."
