Abu `Akasha al-Hamadani

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا أَبُو لَيْلَى، عَنْ أَبِي عُكَّاشَةَ، عَنْ رِفَاعَةَ، قَالَ دَخَلْتُ عَلَى الْمُخْتَارِ فِي قَصْرِهِ فَقَالَ قَامَ جِبْرَائِيلُ مِنْ عِنْدِي السَّاعَةَ ‏.‏ فَمَا مَنَعَنِي مِنْ ضَرْبِ عُنُقِهِ إِلاَّ حَدِيثٌ سَمِعْتُهُ مِنْ سُلَيْمَانَ بْنِ صُرَدٍ عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ ‏ "‏ إِذَا أَمِنَكَ الرَّجُلُ عَلَى دَمِهِ فَلاَ تَقْتُلْهُ ‏"‏ ‏.‏ فَذَاكَ الَّذِي مَنَعَنِي مِنْهُ ‏.‏

It was narrated that Rifa'ah said:“I entered upon Mukhtar in his palace and he said: 'Jibril has just left me.' Nothing stopped me from striking his neck (i.e, killing him) but a Hadith that I heard from Sulaiman bin Surad, according to which the Prophet (ﷺ) said: 'If a man trusts you with his life, then do not kill him.' That is what stopped me.”
