According to Muslim history the roman christians Arch Angel Gabriel appeared to Muhammad and began to squeeze Muhammad until he recited verses of the Koran. This is how the Koran was written.
However there is no such thing as the Arch angel or even the Angel gabriel. Read Daniel in the Old Testament and you shall see that daniel dreamed of a man called Gabriel in a dream. (not in reality)
Chapter 8. In the third year of the reign of King Belshazzar a vision appeared unto Daniel:
The reference that you gave exists in Daniel Chapters 8 verse 15 And it came to pass when I even I Daniel had seen the vision and sought for the meaning then behold there stood before me as the appearance of a man.
Daniel Chapter 8 verse 16: And I heard a mans voice between the banks of Ulai which called and said Gabriel make this man understand the vision. Verse 17: So he came near where I stood and when he came I was afraid and fell upon my face. He said unto me, understand O son of man for at the time of the end shall be the vision. Verse 18: Now as he was speaking with me, I was in a deep sleep on my face toward the ground: But he touched me and set me upright.
Starjade says: So Daniel was in a Dream and saw this vision and he did not see so well with his face buried in the ground and at no time throughout did Daniel ever call Gabriel an Angel but in fact described Gabriel as being a man and further a man that he had dreamed. OK.
Daniel Chapter 9 verse 21: Yea whiles I was speaking in prayer even the man Gabriel whom I had seen in the vision at the beginning being caused to fly swiftly, touched me about the time of the evening oblation.
Starjade says: See at no time does Daniel refer to Gabriel as being an Angel but does describe him as being like a man.
Now skip through the pages to the Christians new Testament which we all know sprang from the Roman Christian period.
Luke Chapter1 verse 19: And the Angel answering said unto him, I am Gabriel that stand in the presence of God and I am sent to thee and to shew thee these glad tidings. Verse 26: And in the sixth month the Angel Gabriel was sent from God unto the city of Galilea named Nazereth:
This is the attempt by the Christians to try and use the name Gabriel as an Angel sent to authenticate Jesus Tsk Tsk Tsk…..
Now according to the Old Testament law of Deuteronomy Ch 19 v 15 which is a witness law that is designed to determine matters of the truth. None of the Testimonies of Jesus have ever been established as being true by Old Testament law in fact he can so easily be proven to be a fraud as I have often shown. But I shall not go into that again here.
Now entertain yourself and go to a Roman catholic Church and ask their priest who is Gabriel mentioned in the bible. His reply will be that Gabriel is the Arch Angel Gabriel head of all Gods angels ( according to stupid roman catholic beliefs. )
However Gabriel was just a Dream of Daniel who at no time ever called Gabriel an Angel. Only the Christians did that and this influenced Muhammad who was told by his wifes cousin (a Christian) that he was a Prophet from God.
The Koran was claimed by Muhammad to have come from the mouth of the invented Gabriel. Which shows just how false Islamic belief is.
