Sulayman bin Buraydah narrates from his father (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) offered five prayers with one ablution on the day of the Conquest of Makkah and wiped over the leather socks. Sayyiduna Umar (may Allah be pleased with him) said to him (peace and blessings be upon him): "I have seen that you (peace and blessings be upon him) did something that you did not do before." He (peace and blessings be upon him) said: "I did it deliberately."
