Sayyiduna Nu’man bin Muqarrin (may Allah be pleased with him) narrates: I was with the Prophet (peace and blessings of Allah be upon him). When he intended to fight in battle, he would not begin fighting in the early part of the day. He would delay it until the sun had declined, the winds had started to blow, and help had descended.
