On Muhammad, my opinion is that he suffered hypothermia in the cold cave up on Mt. Hira, then, as a result, hallucinated an 'angel', suffered 3 heart attacks which he interpreted as the 'angel' squeezing him each time he told the 'angel' that he could't read. Wouldn't a real angel of Allah know that Muhammad couldn't read? Later,he asked his wife to cover him up as he was still suffering from the cold. His wife's cousin told him he must have liaised with the same angel that had contacted Moses. How would HE know?
Further, Jesus NEVER started ANY religion! 'Christianity' is the creation of Paul, a Pharisee and Jesus warned against the Pharisees. An unknown Ananias comes out from nowhere and tells Paul. "Receive thy sight!", then disappears again. Better to corrupt Jesus' teachings than to persecute a few of Jesus' followers at a time. Paul never met Jesus on any road to Damascus and pretended to be blind.
Jesus is alleged to have raised 3 people from the dead. Peter frightened a man and his wife to death. Jesus healed the blind. Paul made a man blind for offering to pay to learn Paul's secrets.
Jesus spoke TRUTH. He said, "God (Allah) is a Spirit: and they that worship him must worship him in spirit and in truth. (John 4: 24)
God is a Spirit, not a ghost but the intangible Living Energy out of whom ALL living energies in the world (whether man, animals, fish, birds, trees, djinns, aliens, etc. come, and recognizing their source from which they enter this physical world, must revere him (him, her, it? Who can know the gender of God, and why would God need gender? I use 'him' only for convenience) and speak TRUTH, for TRUTH proceeds from God.
It is the spirit that quickens (makes the body move). The body is nothing (but recyclable, matter made from part of the living energy). John 6: 63.
We come from the intangible Pure Living Energy (Allah or God) in the Fifth Dimension the world of energy, and return there in dreams and after finally leaving the body in what is called death.
Everyone in the world dreams. The reason many, if not most, people regard dreams as nonsense is because in the Fifth Dimension, the world of Energy, there is no space or time, dimensions of the physical world, therefore no sequencing. Energy moves at the speed of Light.
