No one will deny or dispute the power of the Almighty to make such a communication, if he pleases. But admitting, for the sake of a case, that something has been revealed to a certain person, and not revealed to any other person, it is revelation to that person only. When he tells it to a second person, a second to a third, a third to a fourth, and so on, it ceases to be a revelation to all those persons. It is revelation to the first person only, and hearsay to every other, and consequently they are not obliged to believe it..... When I am told that the Koran was written in Heaven and brought to Mahomet by an angel, the account comes too near the same kind of hearsay evidence and second-hand authority as the former (Book of Exodus). I did not see the angel myself, and, therefore, I have a right not to believe it.
