It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) did not meet the enemy at the beginning of the day, he would delay it until the wind began to blow, and that would be near the times of the prayers. And he (peace and blessings be upon him) would say: "O Allah, by Your help I attack, and by Your help I move about, and there is no might and no power except by Allah."
