When Banu Qurayzah agreed to submit to Saad's judgment, the Messenger of Allah ﷺ sent for him. He was nearby, so he came riding a donkey. When he drew near, the Prophet ﷺ said, "Stand up for your master."
لما نزلت بنو قريظة على حكم سعد، بعث رسول الله ﷺ إليه، وكان قريبا، فجاء على حمار، فلما دنا قال النبي ﷺ: قوموا إلى سيدكم.
Bukhari narrated it in the Book of Jihad and Expeditions (3043), and Muslim narrated it in the Book of Jihad and Expeditions (1768), both from the hadith of Shubah, from Saad bin Ibrahim, from Abu Umama, who is the son of Sahl bin Hunayf, from Abu Saeed Khudri, and he mentioned it.Muslim bin Hajjaj said, "I do not know of a more sahih hadith than this concerning a man standing for another man, and this standing was done as an act of righteousness, not as an act of glorification, the Prophet ordered the Ansar to stand for their leader."Bayhaqi narrated it in "Madkhal" (708) with his chain of transmission back to Muslim bin Hajjaj.Khattabi said in Maalim Sunan (5/390), "A person standing before a virtuous leader, a just ruler, and a student standing for a scholar is recommended and not disliked, the disapproval only applies to those who lack these qualities."
