Musannaf Ibn Abi Shaybah 1882 — Wiping over the leather socks

Sayyiduna Khuzaymah bin Thabit (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) set the period of wiping over the leather socks at three days and three nights for the traveller, and one day and one night for the resident. Had the questioner asked him for more, he would have extended it to five days.
