It is narrated from Sayyiduna Buraidah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) used to perform ablution for every prayer. Then, when the day of the conquest of Makkah came, he performed ablution and wiped over his leather socks and offered several prayers with the same ablution. Sayyiduna Umar (may Allah be pleased with him) said to him, "O Messenger of Allah, today you have done something which you did not use to do before." He (peace and blessings of Allah be upon him) replied, "Umar, I have done this deliberately." (To show that if ablution remains, it is not necessary to perform a new ablution for every prayer.) This is the narration of Abdur Rahman bin Mahdi.
