Musannaf Ibn Abi Shaybah

Hazrat Anas (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) set out towards Khaybar. He (peace be upon him) reached there at night. And whenever the Noble Prophet (peace and blessings be upon him) would reach a people at night, he (peace be upon him) would not attack them until he (peace be upon him) had spent the night and it was morning.
