Misconceptions about Islam

I thought that pretty much all Muslims are Arabs, but it turns out that only 18% are Arab. This surprised me because i thought the Arabs invented Islam. I found out that the two leading Muslim countries are Indonesia and Bangladesh and neither of those countries are Arab countries.

I thought it was kind of weird that Islam does not reject Jesus because they believe in a totally different religon than Christianity. They say that Jesus is a messenger of Allah, so they are pretty much saying that everybody is a messenger to Allah.
