Islam is an Abrahamic, monotheistic faith. Scholars date its creation to the 7th century, but its roots are believed to date back further. Islam is regarded as revealed through Muhammad as the Prophet of Allah. Followers of the Islamic faith are Muslims.
The Quran is Islam's religious text, which Muslims believe to be God's verbatim words and the teaching and normative examples of Muhammad. Muslims also follow a legal system known as Sharia Law, which a faith-cased code of conduct instructing Muslims how to live in almost every aspect of their lives.
Muslims follow five fundamental pillars that are essential to their faith:
- Shahada: to declare one's faith in God and belief in Muhammad
- Salat: to pray five times per day - at dawn, noon, afternoon, sunset, and evening
- Zakat: to give to those in need
- Saw: to fast during Ramadan
- Hajj: to make a pilgrimage to Mecca at least once during a person's lifetime if the person can

Further data shows that these nations contribute about 8% of the world's nominal GDP. The region with the most Muslims is the Middle East-North Africa region.
