Hadith 2828
It is narrated from Sayyida Umm Fadl bint Harith (may Allah be pleased with her) that on the day of Arafah, some of the companions differed in her presence regarding whether the Messenger of Allah (peace and blessings be upon him) was fasting or not. Some said that the Messenger of Allah (peace and blessings be upon him) was fasting, and others said that he was not fasting. So Sayyida Umm Fadl (may Allah be pleased with her) sent a bowl of milk to him while he was seated on his camel. The Prophet (peace and blessings be upon him) drank the milk, and he was in the plain of Arafat on that day.
Hadith 2829
Lady Maymunah (may Allah be pleased with her) narrates this same report from the Messenger of Allah.
