Rivera also made several allegations about Islam, which he did not offer proof for. This includes allegations that Muhammad was manipulated by the Catholic Church to create Islam and destroy the Jews and other groups of Christians, and that Muhammad's first wife Khadijah bint Khuwaylid, was actually a Catholic nun in an Arabian monastery, who was told by a bishop to marry Muhammad and create Islam. Rivera also alleged that the Vatican staged an apparition at Fátima (named after Fatimah, daughter of Muhammad) to cultivate favor with Muslims. He further says that it also staged the 1981 assassination attempt on Pope John Paul II using a Muslim as the marksman "to guilt-induce the Muslim world, bringing them still closer to the Catholic faith!"
