The Church maintains that Jesus (Peace Be Upon Him) is the "Only-begotten Son" of God, and also God Himself, since the doctrine of Trinity considers God as the Son, as the Father and as the "Holy Ghost" all at the same time! Catholics further emphasize the divinity of Mary as the "Mother of God". Islam rejects all these concepts in totality. Allah says in the Noble Qur'an (which is translated as follows):“ Surely, they have disbelieved who say: Allah is the Messiah ['Iesa (Jesus)], son of Maryam (Mary), But the Messiah ['Iesa (Jesus)] said: O Children of Israel! worship Allah, My Lord and your Lord. Verily, whosoever setup partners in worship with Allah, then Allah has forbidden Paradise for him, and the Fire will be his abode. And for the Polytheist and wrong-doers there are no helpers. Surely, disbelievers are those who said: Allah is the third of the three (in a Trinity). But there is no Ilah (God) (none who has the right to be worshipped) but One Ilah (God --- Allah). And if they cease not from what they say, verily, painful torment will befall the disbelievers among them. Will they not repent to Allah and ask His forgiveness? For Allah is Oft-Forgiving, Most Merciful. The Messiah ['Iesa (Jesus)], son of Maryam (Mary), was no more than a Messenger; Many were the Messengers that passed away before him. His mother [Maryam (Mary)] was a Siddiqah [i.e. she believed in the words of Allah and His Books]. They both used to eat food (as any other human being, while Allah does not eat). Look how We make the Ayat (proofs, evidences, verses, lesson, signs, revelations, etc) clear to them, yet look how they are deluded away (from the truth)” [Chapter 5: verses 72-75].
The Muslims rather contend that the miraculous birth of Jesus (Peace Be Upon Him) without a father does not make him a God or a "begotten" son of God. Allah said in the Noble Qur'an (which is translated as follows):“ And they (Jews, Christians and pagans) say: Allah has begotten a son (Children or offspring). Glory be to Him (Exalted be He above all that they associate with Him). Nay, to Him belongs all that is in the heavens and on earth, and all surrender with obedience (in worship) to Him. The Originator of the heavens and the earth. When He decrees a matter, He only says to it: Be! and it is” [Chapter 2: verses
Further Allah says in the Noble Qur'an (Which is translated as follows):“ Say (O Mohammed (Peace Be Upon Him)) He is Allah, (the) One. Allah-us-Samad (The Self-Sufficient Master, Whom all creatures need, He neither eats nor drinks). He begets not, nor was He begotten. And there is none co-equal or comparable unto Him” [Chapter 112 verses 1-4].
The birth of Jesus (Peace Be Upon Him)was not any more supernatural than the creation of our father Adam. Allah said in the Noble Qur'an (Which is translated as follows):“ Verily, the likeness of 'Iesa (Jesus) before Allah is the likeness of Adam. He created him from dust, then (He) said to him: Be! -- and he was” [Chapter 3: verse 59].
