Sahih Bukhari Volume 4, Book 56, Hadith 3044

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 ‏"‏‏

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