Mohammed was AN antiChrist if not the antiChrist. HE is a deceiver who rewrote the Bible to lead the followers of Jesus Christ astray. He is a warlord. His is a political ideology, not a religion. It offers no free will, but slavery.
His is the only major religion to acknowledge the existence of Jesus while at the same time denying His divinity, His crucifixion, and His resurrection. Jesus is replaced by Mohammed (a “superior” prophet).
Weegee: I think John agrees with you:
1 John 2:22 Who is the liar but the person who denies that Jesus is the Christ? This one is the antichrist: the person who denies the Father and the Son.
Qur’an 5:73 “They are surely disbelievers who blaspheme and say: ‘God is one of three in the Trinity for there is no Ilah (God) except One, Allah. If they desist not from saying this (blasphemy), verily a grievous penalty will befall them - the disbelievers will suffer a painful doom.”
