It is narrated from Sayyiduna Khuzaymah bin Thabit Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: You may wipe over the leather socks (khuffs) for three days. If we had asked the Messenger of Allah (peace and blessings be upon him) for a longer concession, he would have granted us a longer concession.
