Musnad Ahmad 32:1542

Ya'qub narrated to us, my father narrated to us, from Muhammad ibn Ishaq, who said: Humayd al-Tawil narrated to me, from Anas ibn Malik al-Ansari: "That the Messenger of Allah, may Allah bless him and grant him peace, when he would reach a village by night, he would not raid until he reached the morning. If he heard the call to prayer, he would refrain; and if he did not hear the call to prayer, he would raid."
