Once, Abdullah bin Umar (may Allah be pleased with them) saw Sa’d bin Malik (may Allah be pleased with him) wiping over his leather socks, so he asked,“Do you also do this?”He replied,“Yes!”Then both of them went together to Umar (may Allah be pleased with him), so Sa’d (may Allah be pleased with him) said,“O Leader of the Believers! Please explain the issue of wiping over leather socks to our nephew.”Umar (may Allah be pleased with him) said,“In the past, we used to wipe over the leather socks with the Prophet (peace and blessings be upon him), and we still do.”Ibn Umar (may Allah be pleased with them) asked,“Even if a person has just come after defecating or urinating?”He replied,“Yes! Even if he has just come after defecating or urinating.”Nafi’ says that after this, Ibn Umar (may Allah be pleased with them) also started wiping over the leather socks and continued to do so until he took them off, and he did not specify any particular time for it.
