Hazrat Ibn Umar (may Allah be pleased with them both) narrates that during the Battle of Qadisiyyah, there was a disagreement between me and Hazrat Sa’d regarding wiping over leather socks (khuffs). He said to wipe over the socks, while I refused. When we presented ourselves before Hazrat Umar, Hazrat Sa’d mentioned this matter to him and said that Ibn Umar (may Allah be pleased with them both) denies wiping over the socks. I said,“O Commander of the Faithful! Hazrat Sa’d says to wipe over the socks after breaking wudu.”Hazrat Umar said,“Wipe after breaking wudu, and wipe even after relieving yourself.”
