This right here is absolute proof that Muhammad was not a true prophet. He did not know God. This is also John's definition of the Antichrist. "He who denies the Father and the Son."
Who is the liar, if it is not the one who denies that Jesus is the Christ? This is the antichrist, who denies the Father and the Son. No one who denies the Son can have the Father; whoever confesses the Son has the Father as well.… 1 John 2:22
