When it is permissible to shed the blood of a muslim
Sahih Muslim
وَحَدَّثَنِي حَجَّاجُ بْنُ الشَّاعِرِ، وَالْقَاسِمُ بْنُ زَكَرِيَّاءَ، قَالاَ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، عَنْ شَيْبَانَ، عَنِ الأَعْمَشِ، بِالإِسْنَادَيْنِ جَمِيعًا . نَحْوَ حَدِيثِ سُفْيَانَ وَلَمْ يَذْكُرَا فِي الْحَدِيثِ قَوْلَهُ " وَالَّذِي لاَ إِلَهَ غَيْرُهُ " .
This hadith has been reported on the authority of A'mash with the same chain of narrators but with a slight variation of words, i. e. he did not say: By Him besides Whom there is no god.
