Yahya related to me from Malik that Said ibn Abd ar-Rahman ibnRuqash said, "I saw Anas ibn Malik come and squat and urinate.Thenwater was brought and he did wudu. He washed his face, then his armsto the elbows, and then he wiped his head and wiped over his leathersocks. Then he came to the mosque and prayed."Yahya saidthat Malik was asked whether a man who did wudu for prayerand then puton his leather socks, and then urinated and took them off and put themback on again, should begin wudu afresh.Malik replied, "Heshould take off his socks and wash his feet. Only someone who puts onleather socks when his feet are (already) ritually purified by wuducan wipe over them. Someone who puts on leather socks when his feetare not ritually purified by wudu, should not wipe over them."Yahya said that Malik was asked about a man who did wudu with hisleather socks on and forgot to wipe over them until the water was dryand he had prayed, and he said, "He should wipe over his socks andrepeat the prayer but not repeat wudu."Malik was asked abouta man who washed his feet and put on his leather socks and thenstarted doing wudu, and he said, "He should take off his socks and dowudu and wash his feet."
