Narrated Tariq bin Shibab: Some Jews said, "Had this Verse been revealed to us, we would have taken that day as `Id (festival)." `Umar said, "What Verse?" They said:-- "This day I have Perfected your religion for you, Completed My Favor upon you And have chosen for you Islam as your religion" (5.3) `Umar said, "I know the place where it was revealed; It was revealed while Allah's Apostle was staying at `Arafat."

Narrated 'Umar bin Al-Khattab: Once a Jew said to me, "O the chief of believers! There is a verse in your Holy Book Which is read by all of you (Muslims), and had it been revealed to us, we would have taken that day (on which it was revealed as a day of celebration." 'Umar bin Al-Khattab asked, "Which is that verse?" The Jew replied, "This day I have perfected your religion For you, completed My favor upon you, And have chosen for you Islam as your religion." (5:3) 'Umar replied,"No doubt, we know when and where this verse was revealed to the Prophet. It was Friday and the Prophet was standing at 'Arafat (i.e. the Day of Hajj)"

Narrated `Abdur-Rahman bin Abi Bakra's father: Once the Prophet was riding his camel and a man was holding its rein. The Prophet asked, "What is the day today?" We kept quiet, thinking that he might give that day another name. He said, "Isn't it the day of Nahr (slaughtering of the animals of sacrifice)" We replied, "Yes." He further asked, "Which month is this?" We again kept quiet, thinking that he might give it another name. Then he said, "Isn't it the month of Dhul-Hijja?" We replied, "Yes." He said, "Verily! Your blood, property and honor are sacred to one another (i.e. Muslims) like the sanctity of this day of yours, in this month of yours and in this city of yours. It is incumbent upon those who are present to inform those who are absent because those who are absent might comprehend (what I have said) better than the present audience."

Narrated Tariq bin Shihab: The Jews said to `Umar, "You (i.e. Muslims) recite a Verse, and had it been revealed to us, we would have taken the day of its revelation as a day of celebration." `Umar said, "I know very well when and where it was revealed, and where Allah's Messenger was when it was revealed. (It was revealed on) the day of `Arafat (Hajj Day), and by Allah, I was at `Arafat" Sufyan, a sub-narrator said: I am in doubt whether the Verse:-- "This day I have perfected your religion for you." was revealed on a Friday or not.
