Muhammad was DEMON POSSESSED

Early Muslim tradition records the fact that when Muhammad was about to receive a revelation from Allah, he would often fall down on the ground, his body would jerk, his eyes would roll backward, and he would perspire profusely.
The scriptures define such an experience with a boy who was demon possessed
(Mark 9:18-20 KJV) And wheresoever he (the demon) take him, he tear him: and he foame, and gnasher with his teeth, and pine away: and I spake to thy disciples that they should cast him (the demon) out; and they could not. He answered him, and saith, O faithless generation, how long shall I be with you? how long shall I suffer you? bring him unto me. And they brought him unto him: and when he saw him, straightway the spirit tare him; and he fell on the ground, and wallowed foaming. "According to extra-Quranic sources, Muhammad's first mystical experience was allegedly being attacked by two men who cut his belly open in search of something. His foster mother thought he was demon-possessed after finding him standing and not having appeared to be the victim of any violence. He later claimed his nonexistent attackers to be angels who cleansed his heart. In a.d. 610, he claimed to have received his first of a series of Revelation of the Quran from God through the angel GABRIEL. His first disciple was his wife, then his cousin Ali, then his slave, and then his friend Abu Bakr. His following grew without many problems: first with slaves and the poor and oppressed, and then some wealthy clans, because, according to some, he used the so-called Satanic verses (a now-deleted version of Sura 53:19 that advocated the worship of the three daughters of Allah; al-Lat, al-'Uzza and Manat, later the angel GABRIEL chided Muhammad for claiming divine inspiration for this verse and told him he did this on his own while under Satan's power) in preaching to the unconverted."

Muhammad claimed that the ANGEL GABRIEL FROM HEAVEN gave him this “OTHER GOSPEL.”
God knew that false prophets like Muhammad would arise to deceive many. He forewarned the saints that, anyone who preaches a different gospel, even if it came from an angel from heaven, is to be "accursed!" Jehovah God had prophesied through Paul, that one day, a man like Muhammad would claim that an angel from heaven gave him another gospel!
(Gal 1:8 KJV) But though we, or an ANGEL from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
(Mat 24:11 KJV) And many false prophets shall rise, and shall deceive many.
(Rev 20:10 KJV) And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
