Musannaf Ibn Abi Shayba 36:292

'Abdullah bin Numayr and 'Abdah narrated to us, from Hisham bin 'Urwah, from his father, from 'Aishah, who said: When the Messenger of Allah (ﷺ) returned on the day of the Trench, and laid down his weapons and performed ghusl, Jibril came to him while his head was covered in dust. He said: "Have you laid down your weapons? By Allah, I have not laid them down." The Messenger of Allah (ﷺ) said: "Where?" He said: "Right here," and he gestured toward Banu Qurayzah. She said: So the Messenger of Allah (ﷺ) went out to them.
