Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Aisha (may Allah be pleased with her) that when the Noble Prophet (peace and blessings be upon him) returned from the Day of the Trench and he had put down his weapons and taken a bath, then Jibreel (Gabriel) came to him and there was dust on his head. He said, "You have put down your weapons. By Allah! I have not put down my weapons." The Messenger of Allah (peace and blessings be upon him) asked, "Then where to?" Hazrat Jibreel replied, "This way!" and he pointed towards Banu Qurayza. The narrator says that then the Noble Prophet (peace and blessings be upon him) set out towards Banu Qurayza.
