WRONG !muslims are predominately arab
About 1.6 billions of people are muslims.
Indonesia : 202,000,000 muslims
Pakistan : 190,000,000
India : 180,00,000
Bangladesh : 150,000,000
So if you do the maths, altogether these 4 countries have about 50% of all the muslims in the world and none of them are arabs.
Stop talking about things you don't know anything about
