Many people don't realize how much the self-proclaimed prophets of Mormonism (Joseph Smith) and Islam (Muhammad) used almost identical techniques to sell their individual false claims that they had received further (and asserted, more important) - revelations from God. As each man basically responded to skeptics and those they deluded with a "trust me" defense concerning their teachings and the sources of their "revelations."
This very important, short video reveals a simple test of four questions that can be applied to both Smith and Muhammad, and how the failure of each to pass the test powerfully exposes them to both be imposters that could provide NO evidence they spoke for God. Everyone should know about this test and how to apply it to anyone asserting to have new revelations from God! See video: https://www.youtube.com/watch?v=lsD8BXG0Vr4
