Kuraib, the freed slave of Ibn 'Abbas (Allaah be pleased with him), reported from Maimuna, the wife of the Prophet of Allaah (sallAllaahu alayhi wa sallam), that people had doubt about the fasting of Allaah's Messenger (sallAllaahu alayhi wa sallam) on the day of 'Arafa. Maimuna sent him a cup of milk and he was halting at a place and he drank it and the people were seeing him.
