عَنْ عِمْرَانَ بْنِ حُصَيْنٍ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَحُثُّنَا عَلَى الصَّدَقَةِ وَيَنْهَانَا عَنِ الْمُثْلَةِ. رَوَاهُ أَبُو دَاوُدَ وَرَوَاهُ النَّسَائِيّ عَن أنس

A’isha reported God’s Messenger as saying, “The blood of a Muslim man who testifies that there is no god but God and that Muhammad is God’s Messenger may lawfully be shed only for one of three reasons

fornication after marriage, in which case he should be stoned; one who goes forth to fight with God and His Messenger,* in which case he should be killed, or crucified, or made a fugitive; or one which commits murder for which he is killed.” Abu Dawud transmitted it.* Mirqat iv. 53 refers this to such things as highway robbery.
