There is only One God, my Muslim friend

The Qur'an teaches that only God can be in heaven and on earth at the same time, saying: "He is God of heaven and the earth." (Cattle 3) 

No creature can have that exclusive attribute of God except the Almighty God. Therefore, it is true that no one can be in the heavens and earth, at the same time, but God. However, the Lord Jesus Christ came to make great wonders and miracles to prove His deity and support His claim that He is the omnipotent and omnipresent God is who is in heaven and on earth at the same time.

The Gospel tells us that the Christ came down from heaven to earth through a divine virgin birth. Also, the Qur'an points out that Christ's birth were unique distinguishing Him from all other men and prophets without exception. If Christ was a mere human being, it would become necessary that His birth be a congenital, sexual birth, from a human father, like the rest of all the humans. But Christ, who made the world, did not need the agent of the human father be born into the world (Mary 16-34).

Also, all the Muslim scholars unanimously agreed that Christ alone is infallible. Al-Bukhari said quoting the prophet of Islam: 

"Satan pokes with his finger the side of every human, at his birth; except Jesus the son of Mary when he went to poke Him, he poked the curtain, instead."

Of all humans, why was only Jesus singled out and given this unique exception in Islam? Had He not been the Almighty God, who came down voluntarily to our world, without the congenital birth, He would not have been given that sole exception. It is evident that it was not befitting God to be born in the natural human way, after the manner of men, which is summed up by David the prophet, saying:

"Behold I was sharpened iniquity, and in sin did my mother conceive me."

This is another reason for Muslims to inquire as to why He could forbid Satan from poking Him. No matter how you study this subject, you will find that Jesus is the Most High God who came down from heaven to earth, at the very time He was in heaven.

John 3:1-13 

Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews.  This man came to Jesus by night and said to him, “Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him.”  Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God." Nicodemus said to him, “How can a man be born when he is old? Can he enter a second time into his mother's womb and be born?”  Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.  That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.  Do not marvel that I said to you, ‘You must be born again.’ The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.” Nicodemus said to him, “How can these things be?” Jesus answered him, “Are you the teacher of Israel and yet you do not understand these things?  Truly, truly, I say to you, we speak of what we know, and bear witness to what we have seen, but you do not receive our testimony.  If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things? No one has ascended into heaven except he who descended from heaven, the Son of Man.
