Musnad Ahmad 32:675

Sulayman narrated to us, Isma'il narrated to us, he said: Humayd narrated to me, from Anas ibn Malik, "That the Prophet, peace and blessings of Allah be upon him, when he would raid a people, he would not raid with us at night until he reached the morning. If he heard the call to prayer (adhan), he would refrain from them, and if he did not hear the call to prayer, he would raid them."
