Shurayh bin Hani narrates: I asked Sayyidah Aisha (may Allah be pleased with her) about wiping over leather socks (khuffs), so she said: Go to Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) and ask him this question, because he used to participate in battles with the Prophet Muhammad (peace and blessings be upon him). The narrator says: I asked Sayyiduna Ali (may Allah be pleased with him) this question, so he said: The Prophet Muhammad (peace and blessings be upon him) used to say: "For a resident, its duration is one day and one night, and for a traveler, three days and three nights."
