1. Muslims believe that Allah revealed the Gospel (Injil) to His Prophet `Isa (Jesus). Muslims also believe that, apart from the Quran, no book remained as it was revealed by Allah, neither the Gospel nor anything else. 2. There are four Gospels, Matthew, Mark, Luke and John. Christians agreed that Luke and Mark did not see the Messiah (peace be upon him), rather he was seen by Matthew and John. The four Gospels were written by these men after the Messiah had been taken up into heaven.

Belief in the Books of Allah implies: 1- Firm belief that all of them were revealed from Allah, 2- The Books that Allah has mentioned by name, we must believe in by name, and those which Allah has mentioned in general terms, we must believe in them in general terms, 3- Believing whatever is true of what they say, and 4- Believing that Allah revealed the Quran as a witness over these Books and to confirm them.
