Hazrat Abu Hayyan (may Allah have mercy on him) narrates that a Sheikh of Madinah Munawwarah said: There was friendship and acquaintance between me and the scribe of Hazrat Ubaidullah. I wrote a letter to him asking that he write to me the letter of Hazrat Abdullah bin Abi Awfa (may Allah be pleased with him) in which he stated: The Messenger of Allah (peace and blessings be upon him) said that you should not ask to meet the enemy. And when you do meet the enemy, then be patient, and know that surely Paradise is under the shade of swords. And the Prophet (peace and blessings be upon him) used to wait; when the sun would decline, he (peace and blessings be upon him) would attack the enemy.

Hazrat Nu’man bin Muqarrin (may Allah have mercy on him) narrates that I was present with the Messenger of Allah (peace and blessings be upon him) in battle. The Messenger of Allah (peace and blessings be upon him) did not engage in fighting during the early part of the day. He delayed the fighting until the sun had declined, the wind had started to blow, and help had descended.
