It is narrated from Sayyidah Aishah (may Allah be pleased with her) that when the Messenger of Allah (peace and blessings be upon him) had finished with the Battle of the Confederates (al-Ahzab), he went inside to take a bath. Just then Jibril (peace be upon him) came and said: "O Muhammad, you have laid down your weapons, but we have not yet laid down ours. Go to Banu Qurayzah." Sayyidah Aishah (may Allah be pleased with her) said: O Messenger of Allah, I saw him through the dust; the dust had wrapped itself around his head.
