Man believers in One God unique without trinity.
4:171. O People of the Scripture! Do not exaggerate in your religion, and do not say about God except the truth. The Messiah, Jesus, the son of Mary, is the Messenger of God, and His Word that He conveyed to Mary, and a Spirit from Him. So believe in God and His messengers, and do not say, “Three.” Refrain—it is better for you. God is only one God. Glory be to Him—that He should have a son. To Him belongs everything in the heavens and the earth, and God is a sufficient Protector.* this is our book . so clear and logic . no contradiction . the Holy Quran
