Where are the highest concentrations of Muslims found? Why might that be?

hi

Explanation:

Muslims are people who follow or practice Islam, a monotheistic Abrahamic religion. Muslims consider the Quran, their holy book, to be the verbatim word of God as revealed to the Islamic prophet and messenger Muhammad. The majority of Muslims also follow the teachings and practices of Muhammad as recorded in traditional accounts. The derivation of "Muslim" is from an Arabic word meaning "submitter".
