Amr bin Wahb al-Thaqafi said: We were with Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him), and he narrated the hadith of the Prophet (peace and blessings be upon him). In it is: "He performed ablution, washed his face and his forearms, wiped his forelock, and also wiped over his khuffs (leather socks) and his turban."
