Dr. Rafat Amari has a weekly TV show, called "Religion and History," on the Alhayat TV channel, which broadcasts to the Middle East. The show is broadcast 16 times weekly. He is often called to be a guest, in the same channel, in a live show, called "Daring question." This is seen by almost 50-70 millions in Middle East and Europe, and considered the most viewed show in Arabic language. Muslims have become aware through his episodes that Islam can't stand when analyzed in light of the historical facts.
