It was narrated that Tariq bin Shihab said:
A Jew said to Umar: 'If this Verse had been revealed to us, we would have taken it as a festival (Eid): This day, I have perfected your religion for you. Umar said: 'I know the day when it was reveled and the night of which it was raveled; a Friday night when we were with Messenger of Allah in Arafat.'"
