Islam is a monotheistic religion articulated by the Qur'an, the sacred text of Islam; it was developed in the Middle East in the 7th century C.E. Islam, and literally means "surrender" or "submission”.
Islam was founded on the teachings of the Prophet Muhammad as an expression of surrender to the will of Allah, the creator and sustainer of the world. The Quran contains the teachings of the Prophet that were revealed to him from Allah.
Adherents of Islam, Muslims, believe that Allah is the one and true God with no partner or equal. Muslims also believe that Islam is the complete and universal version of a primordial faith that was revealed many times before through prophets including Adam, Noah, Abraham, Moses, and Jesus.
Islam has several branches and much variety within those branches. The two divisions within the tradition are the Sunni (75–90%) and Shi'a (10-20%), each of which claims different means of maintaining religious authority.
One of the unifying characteristics of Islam is the Five Pillars, the fundamental practices of Islam. These five practices include a ritual profession of faith, ritual prayer, the zakat (charity), fasting, and the hajj (a pilgrimage to Mecca).
Islam’s birthplace is in the Arabian peninsula, however, now this religion has significant influence in Africa, throughout Asia, Europe, and the Americas. The largest Muslim-majority country (25%) is in South Asia, while 20% of Muslims live in the Middle East, 15% in Sub-saharan Africa and about 13% in Indonesia.
There are over 1,600,000,000 followers (or 23% of earth's population) of Islam in the world. That makes Islam the second-largest religion and one of the fastest-growing major religions in the world.
According to recent estimates, about 50% of Nigerians adhere to Islam (mainly Sunni). Islam dominates in the North and had a number of supporters in the South Western, Yoruba part of the country. Nigeria has the largest Muslim population in sub-Saharan Africa.
