It is narrated from Hazrat Umm al-Fadl that (on the occasion of the Farewell Pilgrimage) on the day of Arafah, the people were in doubt about the fasting of the Prophet (peace be upon him). Hazrat Umm al-Fadl said, "I will find out and inform you." So she sent milk to the Prophet (peace be upon him), and the Prophet (peace be upon him) drank it.
