It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) would launch a raid after the break of dawn. He (peace and blessings be upon him) would listen attentively; if he heard the sound of the adhan, he would stop, otherwise he would attack. One day, he (peace and blessings be upon him) was listening attentively. When he (peace and blessings be upon him) heard the muezzin say: "Allahu Akbar, Allahu Akbar," he (peace and blessings be upon him) said: "They are upon the natural disposition (fitrah)." Then, when the muezzin said: "Ashhadu an la ilaha illallah," he (peace and blessings be upon him) said: "He has been saved from the Fire."

It is narrated from Sayyiduna ‘Isam Muzani, may Allah be pleased with him, who was among the Companions of the Messenger, that when the Noble Prophet, peace and blessings be upon him, would dispatch a military expedition (sariyya), he would say: When you see a mosque or hear the call to prayer (adhan), do not kill anyone. The words of the narrator Ibn ‘Isam are as follows: Sayyiduna ‘Isam, may Allah be pleased with him, said: The Messenger of Allah, peace and blessings be upon him, sent us on a military expedition.
