According to the translators, Jibril speaks in the Koran:
19:64 [Gabriel said], “And we [angels] descend not except by the order of your Lord. To Him belongs that before us and that behind us and what is in between. And never is your Lord forgetful – 65 Lord of the heavens and the earth and whatever is between them – so worship Him and have patience for His worship. Do you know of any similarity to Him?”
Koran 19:64-65
Is Jibril an angel? Let’s check the Koran:
And they say, “Why was there not sent down to him an angel?”
But if We had sent down an angel, the matter would have been decided; then they would not be reprieved.
Koran 6:8
Then would you possibly leave [out] some of what is revealed to you, or is your breast constrained by it because they say, “Why has there not been sent down to him a treasure or come with him an angel?”
But you are only a warner. And Allah is Disposer of all things.
Koran 11:12
Say, “If there were upon the earth angels walking securely, We would have sent down to them from the heaven an angel [as a] messenger.”
Koran 17:95
25:7 And they say, “What is this messenger that eats food and walks in the markets? Why was there not sent down to him an angel so he would be with him a warner? 8 Or [why is not] a treasure presented to him [from heaven], or does he [not] have a garden from which he eats?”
And the wrongdoers say, “You follow not but a man affected by magic.”
Koran 25:7-8
Obviously, Jibril is not an angel due to Allah, Jibril and Muhammad’s denial. Thus the only option left is a demon.
Do other demons speak in the plural like Jibril, through the mouth of their host?
Then Jesus asked him, “What is your name?”
“My name is Legion,” he replied, “for we are many.”
NIV Mark 5:9
Legion, another demon, like Jibril.
Muhammad was a false prophet, for a false god, Allah, for a false religion, Islam, without even a false book, the Koran.
