Revelation of the Verse of Completion of Religion

On the Day of Arafat during the Farewell Pilgrimage, Allah revealed: 'This day I have perfected for you your religion and completed My favor upon you and have approved for you Islam as religion' (5:3). When Umar heard this verse, he wept, sensing it signaled the approaching end of the Prophet's mission and life. A Jewish scholar told Umar that had such a verse been revealed to them, they would have made that day a festival. Umar replied that it was revealed on two Eids: Friday and the Day of Arafat.
