It is narrated from Hazrat Buraidah (may Allah be pleased with him) that on the day of the conquest of Makkah, the Noble Prophet (peace and blessings be upon him) performed several prayers with a single ablution. So Hazrat Umar (may Allah be pleased with him) submitted, "Today you have done something which you have never done before?" The Noble Prophet (peace and blessings be upon him) replied, "I have done this deliberately."
