Why is it that the Islamic religion does not believe that Jesus is the son of God, which was written in the book?
The term ‘son of God’ has been used throughout the Bible in reference to most of the other prophets. In fact, Jesus even taught the followers, as is recorded in the Bible, to pray 'Our father' (this is how it is recorded). 'Our father', in other words, means that we are all from him, so the question of son in the Hebrew language, the phonetic language, indicated closeness to God and not begotten in that sense.
The word ‘begotten’ has been added to the Bible by modern biblical scholars. They have pointed out that this term is an inclusion, as it’s not in the original text. So, in fact, the teaching of Jesus was not that he was the son of God because he has made it clear that the father God was greater than he was and, he in his own practice, he worshiped God. He distinguished himself from God.
So, Islam teaches the distinction between the Creator and His creation, and is based on the fundamental principle found in the Qur'an,
'laysa kamithithlihi shay' 
‘There is nothing like him’
wherein God in no way is like His creation because the creation has sons and God does not have a son. Once you accept the idea that God can have a son, one can come to you and say, “God also has a father and he has a grandfather and uncle”, so where are you going to stop? Why do you stop at the son and not go all the way? Once that door is opened and you say God has a son, what you are doing is that you are taking God down from the level of the Creator and making Him like His creation. Islam keeps God on the level that He deserves to be kept, as the Supreme being, who is distinctly different from His creation. The Quran, the last book of divine revelation, states that God does not have a son. Jesus is quoted in the Quran as saying on the Day of Judgment, when he is asked why he told the people to worship him, he will say that he did not tell the people to worship him, that this is what the people made up after him.
Allah states in the Qur'an:
“And (remember) when Allah will say (on the Day of Resurrection): "O 'Iesa (Jesus), son of Maryam (Mary)! Did you say unto men: 'Worship me and my mother as two gods besides Allah?' " He will say: "Glory be to You! It was not for me to say what I had no right (to say). Had I said such a thing, You would surely have known it. You know what is in my inner-self though I do not know what is in Yours, truly, You, only You, are the All-Knower of all that is hidden and unseen.”
Jesus was a prophet of God, who will according to Islamic teachings return as one of the signs of the Last Day. It is required of Muslims to believe that Jesus, the prophet of God, did not die, that he will come back to the earth as one of the signs of the Last Day, that he will live out his life on the earth, marry, have children and die on earth and will not bring a new revelation as the revelation is complete. He will be the leader of those who submit their will to God on earth.
