They Agreed to Surrender to the Judgement of Saʿd

Still, Banū Qurayẓah, even though they got a hint that this would be their fate, agreed to surrender. But they agreed to surrender when they knew that Saʿd ibn Muʿādh would be the one who would rule in their case. He would be the judge. And Saʿd ibn Muʿādh was their ally in the time of Jāhiliyyah, so they said: fine, well, that's good. If it's going to be Saʿd ibn Muʿādh, and the Messenger of Allah (peace be upon him) is going to give him complete authority to rule among us, then we will surrender. So they surrendered, and they were tied up, and Saʿd ibn Muʿādh was given full authority to rule in their case.

Now Saʿd ibn Muʿādh, it will be remembered, was injured. He was injured during the siege, the Battle of the Trench: he was shot by an arrow in his arm. And Saʿd made a duʿāʾ. He made a duʿāʾ then. His duʿāʾ was, he said: "My Lord, if we are to fight Quraysh again, spare me now for that fight. There are no people I like to fight for Your cause more than those who have opposed Your Messenger, rejected him and forced him out of his hometown. If You have willed that this encounter between us and them would be the last, I pray to You, my Lord, to make this wound of mine my way to martyrdom, but don't let me die until I see our affair with Qurayẓah have a happy ending for Islam." So Saʿd ibn Muʿādh was bitter at what Banū Qurayẓah did when they betrayed the Messenger of Allah (peace be upon him) in the bleakest of moments.

So, Saʿd ibn Muʿādh: the Messenger of Allah (peace be upon him) said, "Bring him." The Messenger of Allah (peace be upon him) had prepared for him a tent in al-Masjid al-Nabawī, and he was placed in that tent so that he could be cared for, and the Messenger of Allah (peace be upon him) would come and visit him, because he was injured and he was lying down. Now his injury was getting better, but he still had to be carried. So they were carrying him, to bring him to the gathering place where the Messenger of Allah (peace be upon him) was, and the Muslims, and the Jews.
