Sayyidah Maymunah (may Allah be pleased with her) narrated that on the day of Arafah, some people doubted whether the Messenger of Allah (peace and blessings be upon him) was fasting, so they (Sayyidah Maymunah, may Allah be pleased with her) sent him some milk. At that time, he was staying at Arafat. He drank that milk while everyone was watching.
