Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) said: One night I was with the Messenger of Allah (peace and blessings be upon him). He (peace and blessings be upon him) dismounted and relieved himself, then he came back, and I poured water for him (peace and blessings be upon him) from a vessel I had with me. He (peace and blessings be upon him) performed ablution and wiped over his leather socks.
