To compile our list and to bring you the correct numbers we used a few sources, most notably Pew Research Center’s study that collected the numbers of Muslim population by country. The study revealed some interesting facts. There are more Muslims in the UK than in Lebanon, and there are more Muslims in China than in Syria, with Syria and Lebanon being majority Muslim countries. They also made a projection to see which countries will have the highest Muslim population in the world by 2050. India will almost double its Muslim population and be the country with the biggest Muslim population in the world.  But 2050 is far away, so here are 11 countries with the  highest Muslim population in the world right now.
