Volume 1, Book 2, Number 43:
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)”
