Ikrimah narrated that pomegranates were brought to Ibn Abbas (may Allah be pleased with them both) on the day of Arafah and he ate them, and Ibn Abbas (may Allah be pleased with them both) said: My mother, Umm al-Fadl (may Allah be pleased with her), told me that the Prophet (peace and blessings be upon him) did not fast on the day of Arafah; she brought him (peace and blessings be upon him) milk and he (peace and blessings be upon him) drank it.
