“They do blaspheme who say: “Allah is Christ the son of Mary.” But said Christ: “O Children of Israel! worship Allah, my Lord & your Lord.” Whoever joins other gods with Allah,- Allah will forbid him the garden, & the Fire will be his abode. There will for the wrong-doers be no one to help.
They do blaspheme who say: Allah is one of three in a Trinity: for there is no god except One Allah. If they desist not from their word (of blasphemy), verily a grievous penalty will befall the blasphemers among them.
Why turn they not to Allah, & seek His forgiveness? For Allah is Oft-forgiving, Most Merciful.
Christ the son of Mary was no more than a messenger; many were the messengers that passed away before him. His mother was a woman of truth. They had both to eat their (daily) food. See how Allah doth make His signs clear to them; yet see in what ways they are deluded away from the truth!
Say: “Will ye worship, besides Allah, something which hath no power either to harm or benefit you? But Allah,- He it is that heareth & knoweth all things.”
Say: “O people of the Book! exceed not in your religion the bounds (of what is proper), trespassing beyond the truth, nor follow the vain desires of people who went wrong in times gone by,- who misled many, & strayed (themselves) from the even way.” [Holy Quran 5:72-77]
