Trinity – Allah, Mary, Jesus

O People of the Book! Do not exceed the bounds of faith nor speak of Allah except in truth. The Messiah, Jesus, son of Mary, was only a messenger of Allah, His word conveyed to Mary, and a spirit from Him. So, believe in Allah and His messengers, and do not say “three.” Stop this, it is better for you. Allah is one, far above having a son.

4:171O People of the Scripture! Do not exaggerate in your religion nor utter aught concerning Allah save the truth. The Messiah, Jesus son of Mary, was only a messenger of Allah, and His word which He conveyed unto Mary, and a spirit from Him. So believe in Allah and His messengers, and say not "Three" - Cease! (it is) better for you! - Allah is only One Allah. Far is it removed from His Transcendent Majesty that He should have a son. His is all that is in the heavens and all that is in the earth. And Allah is sufficient as Defender.
