Sayyidina Jabir reported that, during the Battle of Trenches, Sa’d ibn Mu’adh (RA) was shot by an arrow that severed his artery in the middle of his forearm. The Prophet ‘ branded the wound but his hand swelled. So, he stopped and blood flowed from it. He branded him again, but it swelled again. When he saw that, he prayed, ‘0 Allah, do not take away my soul till my eyes are cooled with Banu Qurayzah,” Blood ceased to flow from his wound and not even a drop came out. Then they chose Sad ibn Mu’adh (RA) as an arbitrator. He was sent for and he judged that their men should be put to death and their women should be spared so that the Muslims might get them to help them. Allah’s Messenger said, ‘You have decided like Allah’s Judgement in their case.” They were four hundred people when he had finished their execution, his wound opened again and blood flowed out, and he died.
