It is narrated from Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that on the day of the Trench, the Asr prayer was missed by the Messenger of Allah (peace and blessings be upon him) because of his engagement in the fighting. He offered the Asr prayer between Maghrib and Isha, and said: "We were kept occupied from the middle prayer. May Allah Almighty fill their graves and their houses with fire."
