It is narrated from Abu Ayyash al-Zuraqi (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) was drawn up in ranks facing the enemy at Usfan, and the idolaters were commanded by Khalid bin al-Walid. The Prophet (peace and blessings be upon him) led them in Zuhr, and the idolaters said: "Now a prayer is coming upon them that is dearer to them than their wealth and their children." So the Messenger of Allah (peace and blessings be upon him) led them in this prayer. He (peace and blessings be upon him) arranged them in two rows behind him, and the Messenger of Allah (peace and blessings be upon him) had them all bow together. When they raised their heads, the near row prostrated while the other row remained standing. When these had raised their heads from prostration, the rear row prostrated with him (peace and blessings be upon him) for their bowing. Then the front row moved back and the rear row moved forward, and each stood in the place of the other. Then he (peace and blessings be upon him) bowed while the others remained standing. When these had finished their prostration, the other row prostrated. Then the Prophet (peace and blessings be upon him) gave them the salam.
