This cannot be Muhammed:
He is living inside of believers.
11. 1 Corinthians 3:16-17 Do you not know that you are God’s temple and that God’s Spirit lives in you? If someone destroys God’s temple, God will destroy him. For God’s temple is holy, which is what you are.
12. 1 Corinthians 6:19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
Scriptures that show that the Holy Spirit is God.
13. Acts 5:3-5 Peter asked, “Ananias, why has Satan filled your heart so that you should lie to the Holy Spirit and keep back some of the money you got for the land? As long as it remained unsold, wasn’t it your own? And after it was sold, wasn’t the money at your disposal? So how could you have thought of doing what you did? You didn’t lie only to men, but also to God!” When Ananias heard these words, he fell down and died. And great fear seized everyone who heard about it.
14. 2 Corinthians 3:17-18 Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. We all, with unveiled faces, are looking as in a mirror at the glory of the Lord and are being transformed into the same image from glory to glory; this is from the Lord who is the Spirit.
The Holy Spirit can be grieved.
16. Ephesians 4:30 And don’t grieve God’s Holy Spirit. You were sealed by Him for the day of redemption.
17. Isaiah 63:10 “Yet they rebelled and grieved his Holy Spirit. So he turned and became their enemy and he himself fought against them.”
This is just a few of the many Scriptures
You don't understand Imamate and Mohammad (s) and his family are with all things and live in all things and lives yes with all human beings inside them, as Quran speaks about the witness in that way, as a close companion in the journey and light of the world, but you keep seeing it one direction, one way, and can't understand holy spirit is actually the spirit of a human being chosen by God on earth right now, and it's the 12th Imam (a) currently who occupies the seat of God and God rules through him.
You have to do some research on the light nature of Imammate of Mohammad (s) and his Successors (a), otherwise, you going to keep this holy spirit 1/3 trinity thing and won't be able to see the perspective I'm speaking about.
The Sufis had this concept as the Qutb (pole) of time and also believed in the 12 Successors of the Prophet (s) to have this position.
In fact there is these options of holy spirit:
It's an Angel.
It's a god
It's God
It's a human being
It's a position occupied by.....
I take the last position, it's a position, it's not one human being that is the holy spirit in all times, nor is it an Angel nor is it a god nor is it God himself, and so it's a position occupied by the chosen human king of a time.
It's leadership that is inward and hidden, light of God just as Jesus said he was the light of the world so long as he was here.
Trinity is invented to obscure the clear name and prophesy in the gospels about Mohammad (s).
