Having debated the concept of Trinity at length with Christians and trying yery much to understand it by logic, I have come to the following conclusions.
1) There is a Trinity in Islam in the form of the Gods message.The Quran is the word of God,the Spirit, and Muhammad.The message is from three entities. The Trinity here is a method rather than a Godhead. It also fulfills the prediction by Jesus in the Gospel John 14:16, 16:7 and 16:13 that there would be another human and spirit with Gods message.These Gospel verses also debunks the concept of the second coming of Jesus himself
Details of the Gospel verses that predicted the coming of the Prophet Muhammad is as follows :-
1.1) John 14:16 "And i will pray the Father,and He will give you another "Comforter",that he may abide with you forever."
1.2) John 16:7 "Nevertheles I tell you the truth.it is expedient for you that I go away, for if I go not away,the Comforter will not come unto you, but if I depart. I will send him unto you.
1.2.1) John 16:8
And when He has come, He will convict the world of sin, and of righteousness, and of judgment:
of sin, because they do not believe in Me;
1.2.3) John 16:10
of righteousness, because I go to My Father and you see Me no more;
(Note:the phrase "you see me no more" is proof that there is no Second coming of Christ)
of judgment, because the ruler of this world is judged.
1.2.5) John 16:12
I still have many things to say to you, but you cannot bear them now.
1.2.6) John 16:13
However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come.
(Note:Jesus refers He to "The Comforter" who is also the Spirit of Truth or that he receives the truth from God via the Spirit of Truth.)
Other evidence of prediction of prophet Muhammad from the Old Testamentare as follows:-
3) Deuteronomy 18:18-19
"I will raise them up a Prophet from among thy brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him. And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him."
(The phrase "from among thy brethren" means from the Ishmael tribe which prophet Muhammad belongs too.)
4)Deuteronomy 33:2 (King James Version)
And he said, The LORD came from Sinai, and rose up from Seir unto them; he shined forth from mount Paran, and he came with ten thousands of saints: from his right hand went a fiery law for them.
(Mount Paran is in Arabia the place where prophet Muhammad came from)
2)The Christian Trinity is an illogical and misunderstood explanation of the process of the Gods message. God,the Holy Spirit and Jesus spoke in unison or as one.The trinity is in the message and miracles of God. Jesus never meant to say that he and the Holy Spirit was God.It was the process of receiving Gods message. he was saying that God spoke through the holy spirit,and himself.So that means the massage and miracles by three identities,Jesus,the Holy spirit and God are one and the same.
Other verses in the Bible confirm that it is by the Father that Jesus can work his miracles and talk about truth.It means that God worked through the Holy Spirit and Jesus himself.Other verses that say Jesus was tempted by the Satan is proof that Jesus was not God and neither was he the Holy Spirit, as God and Holy spirit cannot be tempted. Temptation is only for people with flesh and bones.Verses that say that Jesus was crucified on the cross is also proof that Jesus was human and not God.
The allegory is that the ray and heat of the sun ia a part of the sun but it cannot exist without the sun, as such the ray and the heat is not the sun and not equal to the sun.
Here we can say the Holy Spirit and Jesus is from God but we cannot say that they are God as they would be dead without the life and power given to them by God.
This is how the true logical concept of One God must be understood.
Therefore, Trinity is in the message and the miracles that God lend to Jesus and the Holy Spirit.It means Jesus' miracles and message is the same as the Holy Spirits',and Gods' message and miracles.It is the process rather than the Godhead. God is still one. Jesus and the Holy spirit cannot function without God as such they are creations of God.
If there is any misunderstood aspect of these explanations, please make your comments here and I would gladly respond.
