It is narrated from Mughirah bin Shu'bah (may Allah be pleased with him) that he poured water for the Messenger of Allah (peace and blessings be upon him) from a water-skin. He said: He (peace and blessings be upon him) performed ablution and washed his face - he (peace and blessings be upon him) was wearing a Syrian cloak with a tight sleeve - so he (peace and blessings be upon him) brought out his hands and washed them, and wiped over his turban and his leather socks. Then we came to Abd al-Rahman bin Awf (may Allah be pleased with him) while he was leading the prayer and had already led them in one rak'ah, so we prayed with him the rak'ah that we caught, and we completed the rak'ah that we had missed.
