Sayyiduna Abu Hurairah, may Allah be pleased with him, narrates: The Prophet Muhammad, peace and blessings be upon him, camped between Dajnan and Usfan. The Prophet, peace and blessings be upon him, had besieged the polytheists. The narrator says: Those polytheists said, "This prayer is more beloved to them than their sons and their virgins." They meant the Asr prayer. "So prepare yourselves and launch a single attack upon them." The narrator says: Sayyiduna Jibreel, peace be upon him, came to the service of the Prophet, peace and blessings be upon him, and said: "Divide your companions into two groups. Lead the first group in one rak'ah while the other group keeps their weapons ready. When you have led them in one rak'ah, they should move back and the second group should come forward. Lead them also in one rak'ah, and they should keep their weapons and equipment ready." In this way, each group performed one rak'ah behind the Prophet, peace and blessings be upon him.
