Al-Matalib al-'Aliyah 4280 — Mention of Quraizah

It is narrated from Sayyiduna Abdullah bin Yazid (may Allah be pleased with him) that when the matter of Banu Qurayzah arose, the Messenger of Allah (peace and blessings be upon him) said: "Call your chief to me so that he may judge concerning these servants of Allah", and he (peace and blessings be upon him) meant Sayyiduna Sa'd bin Mu'adh (may Allah be pleased with him). The narrator relates: When he came, he (peace and blessings be upon him) said to him: "Give judgement concerning them." Sayyiduna Sa'd (may Allah be pleased with him) said: "I fear that I may not arrive at the (exact) judgement of Allah, the Mighty and Majestic, concerning them." He (peace and blessings be upon him) said again: "Judge between them." So he pronounced his judgement, and then the Prophet (peace and blessings be upon him) said: "You have judged exactly in accordance with the judgement of Allah, the Mighty and Majestic, and His Messenger."
