O People of the Scripture, do not commit excess in your religion1 or say about Allāh except the truth. The Messiah, Jesus the son of Mary, was but a messenger of Allāh and His word which He directed to Mary and a soul [created at a command] from Him. So believe in Allāh and His messengers. And do not say, "Three"; desist - it is better for you. Indeed, Allāh 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 Allāh as Disposer of affairs.
Translation: Saheeh International (English)
1 Such as attributing divine qualities to certain creations of Allāh or revering them excessively.
Say, O Messenger, to the Christians who received the Gospel: Do not overstep the limits in your religion and do not say anything but the truth about Allah in relation to Jesus. The Messiah, Jesus, son of Mary, is only Allah’s messenger sent with the truth. He created him by His word which He sent with Gabriel to Mary, which was the word ‘Be’, and he became. It was a breath from Allah which Gabriel blew with Allah’s instruction. So have faith in Allah and all His messengers without making a distinction between them. Do not say, ‘The gods are three’. Avoid saying this false statement and it will be better for you in this world and the Afterlife. Allah is the only One God free of any partner or child. He is Self-sufficient. The dominion of the heavens, the earth and whatever is in between the two is His. He is sufficient as a guardian to carry out the affairs of His creation.
