It was narrated from 'Aishah that:The Messenger of Allah [SAW] said: "It is not permissible to shed the blood of a Muslim except in three cases: An adulterer who had been married, who should be stoned to death; a man who killed another man intentionally, who should be killed; and a man who left Islam and waged war against Allah, the Might and Sublime, and His Messenger, who should be killed, or crucified, or banished from the land."
أَخْبَرَنَا الْعَبَّاسُ بْنُ مُحَمَّدٍ الدُّورِيُّ، قَالَ حَدَّثَنَا أَبُو عَامِرٍ الْعَقَدِيُّ، عَنْ إِبْرَاهِيمَ بْنِ طَهْمَانَ، عَنْ عَبْدِ الْعَزِيزِ بْنِ رُفَيْعٍ، عَنْ عُبَيْدِ بْنِ عُمَيْرٍ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ إِلاَّ بِإِحْدَى ثَلاَثِ خِصَالٍ زَانٍ مُحْصَنٌ يُرْجَمُ أَوْ رَجُلٌ قَتَلَ رَجُلاً مُتَعَمِّدًا فَيُقْتَلُ أَوْ رَجُلٌ يَخْرُجُ مِنَ الإِسْلاَمِ يُحَارِبُ اللَّهَ عَزَّ وَجَلَّ وَرَسُولَهُ فَيُقْتَلُ أَوْ يُصْلَبُ أَوْ يُنْفَى مِنَ الأَرْضِ " .
