Silsilah as-Sahihah 412 — Duration and rulings of wiping over socks

It is narrated from Sayyiduna Khuzaimah bin Thabit Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Wipe over the leather socks for three days." If we had asked for more (days), he (peace be upon him) would have granted us permission for more (days).
