Where does Jesus say I am NOT God in the Qur’an?
Question:
Muslims often like to ask where did Jesus claim to be God in the Bible, to prove that he isn’t God. Some Christians have decided to ask us, “where does Jesus say he is not God in the Qur’an?,” they are trying use our own argument against us. How can we respond to this?
Answer:
Unfortunately for the Christian, Jesus in the Qur’an rejects that he ever claimed to be God, therefore asking this question as a counter-argument is not very smart to say the least. In Qur’an 5:116, it is stated:
“And [beware the Day] when Allah will say, “O Jesus, Son of Mary, did you say to the people, ‘Take me and my mother as gods besides Allah?’” He will say, “Exalted are You! It was not for me to say that to which I have no right. If I had said it, You would have known it. You know what is within myself, and I do not know what is within Yourself. Indeed, it is You who is Knower of the unseen.”
If a missionary uses this argument, and they’re serious about it, I’d personally find someone smarter to talk to.
and Allah knows best.
Calling Christians 
Refusing to call Jesus son of God or God is not done with a view to belittle Jesus. No! On the contrary, it is done to Glorify God, to magnify His name, and to proclaim His transcendent majesty.
“The Messiah, son of Mary, was not but a messenger; [other] messengers have passed on before him. And his mother was a supporter of truth. They both used to eat food. Look how We make clear to them the signs; then look how they are deluded.”
[Qur’an 5:75]
