4:171

يَا أَهْلَ الْكِتَابِ لَا تَغْلُوا فِي دِينِكُمْ وَلَا تَقُولُوا عَلَى اللَّهِ إِلَّا الْحَقَّ إِنَّمَا الْمَسِيحُ عِيسَى ابْنُ مَرْيَمَ رَسُولُ اللَّهِ وَكَلِمَتُهُ أَلْقَاهَا إِلَىٰ مَرْيَمَ وَرُوحٌ مِّنْهُ فَآمِنُوا بِاللَّهِ وَرُسُلِهِ وَلَا تَقُولُوا ثَلَاثَةٌ انتَهُوا خَيْرًا لَّكُمْ إِنَّمَا اللَّهُ إِلَٰهٌ وَاحِدٌ سُبْحَانَهُ أَن يَكُونَ لَهُ وَلَدٌ لَّهُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ وَكَفَىٰ بِاللَّهِ وَكِيلًا

Word by Word:

O People (of) the Book! (Do) not commit excess in your religion and (do) not say about Allah except the truth. Only the Messiah, Isa, son (of) Maryam, (was) a Messenger of Allah and His word which He conveyed to Maryam and a spirit from Him. So believe in Allah and His Messengers. And (do) not say, "Three;" desist (it is) better for you. Only Allah (is) God One. Glory be to Him! That He (should) have for Him a son. To Him (belongs) whatever (is) in the heavens and whatever (is) in the earth. And Allah is sufficient (as) a Disposer of affairs.

Translations:

O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God.

O People of the Book! Commit no excesses in your religion: Nor say of God aught but the truth. Christ Jesus the son of Mary was (no more than) an apostle of God, and His Word, which He bestowed on Mary, and a spirit proceeding from Him: so bel ieve in God and His apostles. Say not "Trinity" : desist: it will be better for you: for God is one God: Glory be to Him: (far exalted is He) above having a son. To Him belong all things in the heavens and on earth. And enough is God as a Disposer of a ffairs.

O 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.

O People of the Book, exceed not the limits in your religion or speak anything about Allah, but the truth. The Messiah, Jesus, son of Mary, is only a messenger of Allah and His word which He communicated to Mary and a mercy from Him. So believe in Allah and His messengers. And say not, Three. Desist, it is better for you. Allah is only one God. Far be it from His glory to have a son. To Him belongs whatever is in the heavens and whatever is in the earth. And sufficient is Allah as having charge of affairs.

O People of the Scripture, do not commit excess in your religion or say about Allah except the truth. The Messiah, Jesus, the son of Mary, was but a messenger of Allah and His word which He directed to Mary and a soul [created at a command] from Him. So believe in Allah and His messengers. And do not say, "Three"; desist - it is better for you. Indeed, Allah is but one God. Exalted is He above having a son. To Him belongs whatever is in the heavens and whatever is on the earth. And sufficient is Allah as Disposer of affairs.
