When the Prophet (peace and blessings of Allah be upon him) finished relieving himself, Sayyiduna Mughirah (may Allah be pleased with him) poured water over (the blessed limbs of) the Prophet (peace and blessings of Allah be upon him) while he performed ablution, and the Prophet (peace and blessings of Allah be upon him) wiped over his leather socks.

At that time, he was wearing a Syrian cloak. He wanted to roll up the sleeve to uncover his hand, but it was tight, so he brought his hand out from inside the sleeve. I poured water over his hands; the Messenger of Allah (peace and blessings be upon him) performed ablution as for prayer and wiped over his leather socks (khuffain), then he prayed.

Then he returned, and I gave him water from a vessel to use. The Prophet (peace and blessings of Allah be upon him) washed his face and his hands. He was wearing a woolen cloak, the sleeves of which were difficult for him to roll up, so he brought his hands out from under the cloak and washed his arms up to the elbows.

So he wiped over them.
