I do not believe in the Qur'an but you do so I will talk about the Qur'an with you.
I will start with John 1:33. The verse says, "And I myself did not know him, but the one who sent me to baptize with water told me, ‘The man on whom you see the Spirit come down and remain is the one who will baptize with the Holy Spirit.’"
In this verse, God told John the Baptist about His Son and the Holy Spirit, giving a perfect picture of the Holy Trinity. In the same way, the same picture is reflected not once but twice in the Qur'an when God was quoted as saying: "And We gave Jesus son of Mary the clear signs, and confirmed him the Holy Spirit." (The Cow 87). Also, the verse in the Surah of Women 171 describes Jesus saying: "His Word that He committed to Mary, and a spirit from Him."
If we study those two Qur'an verses, we find that the Speaker was God addressing His Word and supporting Him with His Holy Spirit-no prophet ever was giving that privilege.
This is great assurance that the Qur'an did not deviate from reiterating the Gospel's teaching, confirming the reality of the Holy Trinity, ie., God the Father, the Word and the Holy Spirit.
