Muhammad had a diabolical aversion to the form of the cross.  

Symptomatic of the state of Muhammad's soul during his lifetime is the strikingly similar behavior regarding the cross that demons have demonstrated over and over.

According to Al Waqidi, Muhammad would break everything brought into the house with a shape of the cross on it.   Additionally, Ahmad ibn Hanbal (A.D. 855) said that Muhammad would foam at the mouth during prayer.  Christians should immediately remember the Apostle Mark's telling of Jesus casting a demon out of a boy who was possessed. This demon-possessed boy also showed this symptom of "foaming at the mouth".   

More than eight hundred million human beings confess Islam, the religion Muhammad founded. There is no more militant movement on earth equal to Islam.  No religion teaches hatred more than Islam.  Jesus said; "many false prophets will rise up and deceive man." Islam has managed to turn billions of people away from the true Word of God, and not merely by its distraction of the truth. But also by its outright denial of the truth.
