What is the Muslim population in 2013?

Answer 1

I will be honest, I don't call anyone Muslims because of a name they have or because they call themselves Muslims or because they speak Arabic. You should all know what the word Muslim means, Muslim means someone that is believing in Allah and his prophet, and believes that there is no God but Allah and there is no prophet after Muhammad.

Many who call themselves Muslims, believe there is a prophet after Muhammad pbuh and those who believe things like that are out of Islam or are not Muslims. So I will talk about the Sunni Muslims. Sunni Muslims believe in Allah and his prophet Muhammad and that there is no prophet after Muhammad and no God but Allah. But many actually never pray, never fast, never opened the Quran, but still call themselves Muslims. The Sunni Muslim population is 1.5 billion worldwide, but only 0.5% to 2% are true Sunni Muslims.

That is right, there are 15 million true Muslims only and this is what I care about. This is what I will count and I don't care about the ones who call themselves Muslims and never follow Islam.

The true Muslim population is 15 million, Just 0.21% of the global population. This is probably the real Muslim population for me.
