The Quran teaches falsely. Muslims believe that the Holy Spirit is the archangel Gabriel. I have seen the Holy Spirit myself and will show you photos and a biblical painting of Him. And, I will include scripture to demonstrate that these images are truly the Holy Spirit of the Holy Bible.
Identifying the Holy Spirit
This is a photograph of the Holy Spirit descending like a dove as He did during the baptism of Jesus.
Here is a photograph of the Holy Spirit motionless.
Below is a painting of the Apostle Saint Andrew with the Holy Spirit upon Him.
The Halo is found in scripture as the Holy Spirit alighting and remaining upon Jesus.
The Spirit of God and the Spirit are both one and the same Holy Spirit.
Mathew 3:16. When He had been baptized, Jesus came up immediately from the water, and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and alighting upon Him.
John 1:32. John testified saying, “I have seen the Spirit descending as a dove out of heaven, and He remained upon Him.”
The center photograph above is of the Holy Spirit in His spiritual bodily form.
Luke 3:22. And the Holy Spirit descended in bodily form like a dove upon Him,
and a voice came from heaven which said, “You are My beloved Son; in You I am well pleased.”
The Holy Spirit alighting and remaining upon Jesus appeared as a Halo.
