Shuraih bin Hani says that I asked Sayyida Aisha Siddiqa (may Allah be pleased with her) a question regarding wiping over the socks, so she said, "You should ask this question to Sayyiduna Ali (may Allah be pleased with him); he has more knowledge about this issue." So I asked Sayyiduna Ali (may Allah be pleased with him), and he said, "The Prophet (peace and blessings be upon him) used to command us to wipe over the socks for one day and night, and for the traveler, three days and three nights."
