(18) زِيَادَةُ الْإِيمَانِ
It was narrated that Tariq bin Shihab said:
"A Jewish man came to 'Umar bin Al-Khattab and said: 'O Commander of the Believers! There is a Verse in your Book which you recite; if it had been revealed to us Jews we would have taken that day as a festival.' He said: 'Which Verse is that?' He said: 'This day, I have perfected your religion for you, completed My favor upon you, and have chosen for you Islam as your religion.' 'Umar said: 'I know the place where it was revealed and the day on which it was revealed. It was revealed to the Messenger of Allah [SAW] at 'Arafat, on a Friday.'"
