Holy Spirit not a Part of Trinity

📖Quran 4:171
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.

• The Christians have no proof for their claim to be honouring ‘Jesus (peace be upon him) with regard to the Spirit being mentioned in conjunction with God, because this is also mentioned with regard to things other than him.

📖Numbers 11:16-17

• In the Old Testament it says that God said to Moses  I will take some of the power of the Spirit that is on you and put it on them.

📖Genesis 41:38

• It also says that Pharaoh know that Joseph also received the spirit from God

📖Daniel 5:14

The spirit is creation of God

📖Psalm 104:30
New International Version
When you send your Spirit, they are created, and you renew the face of the ground.

📖Psalm 104:4
He God makes the spirits his messengers, flames of fire his servants.

• Angels are called “spirits” or “winds”, Psalm 104:4 they are created spirits (Psalm 104:30) the angels also called Messengers malak and so differ from God; are incorporeal ones, and so differ from men; and are immaterial and immortal, and so die not: they are spiritual subsistences, and spirits of the heavens, or heavenly spirits.

📖Riyad as-Salihin 1846
The Messenger of Allah (ﷺ) said, “Angels were created from light, jinns were created from a smokeless flame of fire, and ‘Adam was created from that which you have been told (i.e., sounding clay like the clay of pottery).

• In Islamic traditions, the angels are described as being created from incorporeal light (Nur)

📖Zechariah 6:5
The angel answered me, “These are the four spirits of heaven, going out from standing in the presence of the Lord of the whole world.

• If the spirit is a manifestation of God Himself, as Christians put it, then how are there four manifestations of God standing in the presence of God, and then going out from His presence? So the Book of Zechariah clearly indicates that spirits are entities other than God. The interpretation of four angels makes much more sense here. Many respectable Bible commentaries interpret the four spirits (‘ruwach’) as four angels. For instance, Scofield Reference Notes states in its commentary on Zechariah 6:5: That which is symbolized by the four chariots with their horses is not the four world-empires of Daniel, but ‘the four spirits of heaven which go forth from standing before the Lord of all the earth…’ These ‘spirits’ are angels. The commentary Albert Barnes’ Notes on the Bible agrees: These are the four spirits of the heavens – They cannot be literal winds: for spirits, not winds, stand before God, as His servants, as in Job 1:6 , ‘the sons of God [angels] came to present themselves before the Lord.

Zechariah 6:5 standing in the presence of the Lord ?

📖Luke 1:19
The angel said to him, “I am Gabriel. I stand in the presence of God, and I have been sent to speak to you and to tell you this good news.

• luke 1:19 The angel Gabriel stand in the presence of God, It is mentioned in the Zachariah Verse 6:5 that four spirits stand presence of the Lord, including the Archangel Gabriel which we see in Luke 1:19, And am sent … – The angels are “ministering spirits” sent forth to minister for them who shall be heirs of salvation,” Hebrews 1:7, Hebrews 1:14 They delight to do the will of God. This clearly shows that the Spirit is an angel & the Holy Spirit is a archangel Gabriel who brings revelation, and that ‘Jesus (peace be upon him), the “Lord’s Christ (i.e., Messiah)” is a servant of God. God is the One Who anointed him and made him the Christ/Messiah.
