The Muslims that are Sunni Muslims, are 85 to 90 percent of the Muslims in the world, the largest religious sect in the world, and their goal is world domination, the balance are called Shia Islam followers.
They will gain world domination strictly by numbers.
The growth of the Muslim population also is helped by the fact that Muslims have the youngest median age (24 in 2015) of all major religious groups, more than seven years younger than the median age of non-Muslims (32).
A larger share of Muslims will soon be at the point in their lives when people begin having children. This, combined with high fertility rates, will accelerate Muslim population growth.
