Praise be to Allaah.We have previously explained that the Gospel in which we believe, and no one's Islam is valid unless he believes in it, is not the gospels that are in the hands of the Christians nowadays. Rather the Gospel in which we believe is that which was brought by ‘Eesa (Jesus – peace be upon him) from Allaah. As for that which is in the hands of the Christians today, it is something else, and they themselves do not claim that Jesus is the one who brought it or wrote it. See question no. 47516.

As that is the case, what the Christians claim about the Gospels stating that Jesus is the son of God and that God is his father –exalted be Allaah above having a son or a wife – does not count as any kind of proof against us, because we believe that that is something that was fabricated by human beings, and it is not part of the religion of Jesus (peace be upon him) or the religion of any other Messenger.

We believe that the Gospels that are in people’s hands today, in which the Christians believe, have been tampered with and changed, and are still being tampered with from time to time, so that there is nothing left in the form in which the Gospel was revealed from Allaah. Here we would point out that the Gospel which speaks most of the belief in the trinity and the divinity of the Messiah (peace be upon him), so that it has become a reference-point for the Christians in their arguments in support of this falsehood, is the Gospel of John. This Gospel is subject to doubts about its authorship even among some Christian scholars themselves, as is not the case with the other Gospels in which they believe. This is an ancient doubt which goes back to the second century CE according to their own history.

Professor Stadlin says: The entire Gospel of John was written by one of the students of the Alexandrian school. One sect, in the second century, rejected this Gospel and everything that was attributed to John.

In the Encyclopaedia Britannica it says:

As for the gospel of John, it is undoubtedly fabricated. Its author wanted to pitch two of the disciples against one another, namely St. John and St. Matthew.

This writer who appears in the text claimed that he was the disciple who was loved by the Messiah, and the Church took this at face value and affirmed that the writer was the disciple John, and it put his name on the book, even though the author was not John for certain. This book is like the books of the Torah, in that there is no connection between them and the one to whom they are attributed. We feel sorry for those who did their utmost to make the connection, between this philosopher who wrote the book in the second century, and the disciple John the fisherman, for their efforts were to no avail and with no guidance.

Quoted from Muhaaraat fi’l-Nasraaniyyah by Shaykh Muhammad Abu Zahrah.

It is strange indeed that they cast aspersions on the authorship of this Gospel which they affirm was written especially to support this falsehood, the false belief in the divinity of the Messiah, which is ignored in the other gospels, until this gospel was written, at the least. Yoosuf al-Khoori says: John wrote his Gospel at the end of his life, at the request of the bishops of Asia and elsewhere. The reason for that is that there were sects that denied the divinity of the Messiah, so they asked him to prove it, and to highlight that which Matthew, Mark and Luke had neglected in their Gospels.

Regardless of the doubts about the authorship of the Gospels in general, and of the Gospel of John in particular, the phrases that they quote from these Gospels do not support the point they are trying to make, rather it is a spider’s web to which they are clinging, as Allaah says of them and others like them (interpretation of the meaning):

“The likeness of those who take (false deities as) Awliya’ (protectors, helpers) other than Allaah is the likeness of a spider who builds (for itself) a house; but verily,
