It is narrated from Sayyiduna Ali (may Allah be pleased with him) that on the day of the Battle of Khandaq, the Prophet (peace and blessings be upon him) said: "May Allah fill the homes and graves of these polytheists with fire, for they did not allow us to perform the Asr prayer until the sun had set."
