Allah the Exalted warned: Surely they have disbelieved who say: 'Allah is the Messiah (Jesus), son of Mary." But the Messiah (Jesus) said: "O Children of Israel! Worship Allah, my Lord and your Lord." Verily whosoever sets up partners in worship with Allah, then Allah has forbidden Paradise for him, and the Fire will be his abode. And for the Zalimun (polytheists 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 a 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 (Jesus), son of Mary, was no more than a Messenger; many were the Messengers that passed a way before him. His mother (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, lessons, signs, revelations, etc.) clear to them, yet look how they are deluded a way (from the truth). Surah 6: 72-75
