4:171. O People of the Scripture! Do not exceed the limits in your religion, nor say of Allah except the truth. Al-Masih `Isa, son of Maryam, was (no more than) a Messenger of Allah and His Word, which He bestowed on Maryam and a spirit from ﴿created by﴾ Him; so believe in Allah and His Messengers. Say not: "Three!'' Cease! (it is) better for you. For Allah is (the only) One God, hallowed be He above having a son. To Him belongs all that is in the heavens and all that is in the earth. And Allah is All-Sufficient as a Disposer of affairs.)
