Allah(God)
Answer-2
Almighty Allah had been revealing sacred books to His Prophets (May peace be upon them all). The Tora, the Zaboor, The Bible are more famous than a few others. The last of all - the Holy Qur'an - was revealed to the last Prophet Hazrat Muhammad (SAW). It is the Guidance provided to all mankind by Almighty Allah. It was revealed through the Arch Angel Hazrat Gabriel (AS).
1) The messages given were contradictory: Gabriel gave a message to Mary, the mother of Jesus, that Jesus would be called the Son of God (Luke 1:35). Gabriel gave a message to Prophet Daniel that Messiah would die for sins (Dan 9:24-26). The spirit that spoke to Mohammad gave a contradictory message. Hence the Biblical Gabriel did not speak to Mohammad.
2) The Biblical figures knew who appeared to them, Mohammad did not: Daniel, Zachariah and Mary knew that it was Gabriel who appeared to them (Daniel 9:21, Luke 1:19, Luke 1:26-35). Mohammad was not aware of who spoke to him at the Cave of Hira. It was the opinion of his wife Kadijah and his cousin Waraqa that made Mohammad to believe that it was Gabriel of the Bible who spoke to him.
3) The Biblical figures were never forced to do anything by Gabriel but Mohammad was forcefully pressed down to the ground: This spirit who spoke to Mohammad pressed him down forcefully and asked him to recite, to which the terrified Mohammad replied I cannot recite. This ordeal repeated three times!
4) The spirit was ignorant that Mohammad could not read : The spirit asked three times Mohammad to read. A real angel of God should have known that he do not know how to read.
5) Mohammad was terrified even hours after this spirit spoke to him: Mohammad had to go to Kadijah, his first wife, terrified and said "Cover me, cover me." This experience of fear was with Mohammad several days. This was never the case of Biblical prophets like Moses, Daniel or Elijah when angels spoke to them. Biblical figures were not fearful after the Gabriel talked to them.
6) Mohammad had suicidal thoughts after Jibriel's visit at the Cave of Hira: Mohammad was on the way to a mountain to throw himself down to commit suicide after Jibriel visitation. Biblical prophets never had this behavior after being visited by Gabriel.
7) Mohammad had revelations from Satan: Surah 22:52 is described as satanic verses as in the Salman Rushdie's book. Islamic interpretation of this verse in Ibn Kathir 1999 Printing, V5, P441 says that satan cast into Mohammad's mouth Surah 53:19-20 and he bowed down to idols. Biblical prophets such as Moses, Daniel or David never had revelations from Satan.
All these evidences show that Gabriel from God did to give messages to Mohammad. He might have had a visit from an angel of Satan who can come as an angel of Light. Bible says: And no wonder! For Satan himself transforms himself into an angel of light (2Cor11:14). Satan is always against God's plan. Satan wanted to deceive millions of people by turning them from Jesus Christ who died for their sins to give them heaven.
