Sahih al-Bukhari 6262

Abu al-Walid narrated to us: Shubah narrated to us, from Sad ibn Ibrahim, from Abu Umamah ibn Sahl ibn Hunayf, from Abu Said: The people of Qurayzah submitted to Sad’s judgment, so the Prophet, peace and blessings be upon him, sent for him. He came, and the Prophet said, ‘Stand for your leader’—or he said, ‘your best man.’ He sat beside the Prophet, who said, ‘These people have submitted to your judgment.’ Sad said, ‘I judge that their fighting men be killed and their children taken captive.’ The Prophet said, ‘You have judged according to the judgment of the Sovereign.’ Abu Abdullah said: One of my companions helped me understand that Abu al-Walid’s version from Abu Said said, ‘They submitted to your judgment.’
