Sahih al-Bukhari 56:249
Narrated Abu Sa`id Al-Khudri:
When the tribe of Bani Quraiza was ready to accept Sa`d's judgment, Allah's Messenger (ﷺ) sent for Sa`d who was near to him. Sa`d came, riding a donkey and when he came near, Allah's Messenger (ﷺ) said (to the Ansar), "Stand up for your leader." Then Sa`d came and sat beside Allah's Messenger (ﷺ) who said to him. "These people are ready to accept your judgment." Sa`d said, "I give the judgment that their warriors should be killed and their children and women should be taken as prisoners." The Prophet (ﷺ) then remarked, "O Sa`d! You have judged amongst them with (or similar to) the judgment of the King Allah."

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا شُعْبَةُ، عَنْ سَعْدِ بْنِ إِبْرَاهِيمَ، عَنْ أَبِي أُمَامَةَ ـ هُوَ ابْنُ سَهْلِ بْنِ حُنَيْفٍ ـ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ـ رضى الله عنه ـ قَالَ لَمَّا نَزَلَتْ بَنُو قُرَيْظَةَ عَلَى حُكْمِ سَعْدٍ ـ هُوَ ابْنُ مُعَاذٍ ـ بَعَثَ رَسُولُ اللَّهِ صلى الله عليه وسلم، وَكَانَ قَرِيبًا مِنْهُ، فَجَاءَ عَلَى حِمَارٍ، فَلَمَّا دَنَا قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " قُومُوا إِلَى سَيِّدِكُمْ ". فَجَاءَ فَجَلَسَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ لَهُ " إِنَّ هَؤُلاَءِ نَزَلُوا عَلَى حُكْمِكَ ". قَالَ فَإِنِّي أَحْكُمُ أَنْ تُقْتَلَ الْمُقَاتِلَةُ، وَأَنْ تُسْبَى الذُّرِّيَّةُ. قَالَ " لَقَدْ حَكَمْتَ فِيهِمْ بِحُكْمِ الْمَلِكِ ".
