Narrated Jabir: I heard the Prophet saying, "The Throne (of Allah) shook at the death of Sa`d bin Mu`adh." Through another group of narrators, Jabir added, "I heard the Prophet : saying, 'The Throne of the Beneficent shook because of the death of Sa`d bin Mu`adh."

Narrated Abu Sa`id Al-Khudri: Some people (i.e. the Jews of Bani bin Quraiza) agreed to accept the verdict of Sa`d bin Mu`adh so the Prophet sent for him (i.e. Sa`d bin Mu`adh). He came riding a donkey, and when he approached the Mosque, the Prophet said, "Get up for the best amongst you." or said, "Get up for your chief." Then the Prophet said, "O Sa`d! These people have agreed to accept your verdict." Sa`d said, "I judge that their warriors should be killed and their children and women should be taken as captives." The Prophet said, "You have given a judgment similar to Allah's Judgment (or the King's judgment).
