What did the Prophet Muhammad (saw) say on the day of the Battle of Ahzab regarding the 'Asr prayer?
 'Ali reported:                      The Messenger of Allah (may peace be upon him) said on the day (of the Battle) of Ahzab: They diverted us from saying the middle prayer, i. e. the 'Asr prayer. May Allah fill their houses and graves with fire; he then observed this prayer between the evening prayer and the night prayer.
