Those who said: if you hear the adhan, stop fighting

A man of the tribe of Muzaynah reports from his father that whenever the Prophet (peace and blessings be upon him) sent out an army, he (peace and blessings be upon him) would say to them: "When you see a mosque or hear the voice of a mu'adhdhin, do not kill anyone."

Sayyiduna Anas (may Allah be pleased with him) said: Whenever the Prophet (peace and blessings be upon him) came to a people at night, if he (peace and blessings be upon him) heard the adhan, he (peace and blessings be upon him) would refrain from fighting.

Abu al-Aliyah (may Allah have mercy on him) said that whenever Sayyiduna Abu Bakr (may Allah be pleased with him) sent an army against the apostates, he would say: "Sit down near the settlement. If you hear the sound of the adhan by the time the sun rises, then all is well; otherwise, attack them."
