Abdur Rahman bin Abi Laila says that I was once with Sayyiduna Bara bin Azib (may Allah be pleased with him), at that time Sayyiduna Umar (may Allah be pleased with him) was looking at the moon in Jannat al-Baqi when a rider came and Sayyiduna Umar (may Allah be pleased with him) encountered him. He asked him, "Are you coming from somewhere?" He replied, "From the west." He asked, "Did you see the moon?" He said, "Yes! I have seen the moon of Shawwal." Sayyiduna Umar (may Allah be pleased with him) said Allahu Akbar and declared, "The testimony of one man is sufficient for the Muslims." Then he himself stood up, performed ablution from a vessel containing water, wiped over his leather socks, and led the Maghrib prayer. He said, "I saw the Prophet (peace and blessings be upon him) doing the same. At that time, the Prophet (peace and blessings be upon him) was wearing a Syrian cloak with tight sleeves, and the Prophet (peace and blessings be upon him) took his hands out from under the cloak and wiped over (the socks)."
