Protection Of Quran's Transmission From The Jinns
The Arch Angel Jibraeel, (The most powerful creation of Allah Talla) guards every Revelation from the Jinns while delivering to all the prophets. The Prophecy can be corrupted by Iblees & his shyateen if left unguarded which is what happened to the prophecies given by Fortune-tellers and Star worshippers during the time of the last Prophet. Similarly during ancient times and even today Hindu Mystics, Sufis, Gurus etc are influenced by these corrupted prophecies by Jinns and shayateen upon which they inherit esoteric(hidden/inner) meaning of Revelation.(Quran/Bible/BhagvadGita etc)
But why all these mystics came to the conclusion that there is something that exists and they call it “pure consciousness” .They all come to the conclusion of the existence of one God.
