Islam (whose followers are known as Muslims) is the most popular religion in the world, with 1.8 billion followers. They worship in a mosque and their God is known as Allah. There are two different denominations of Islam: Sunni and Shi’a. They each believed that a different person should have lead Islam after Muhammad, the last prophet, died.
If you have been or are planning to go to a mainly Muslim country, such as Turkey and are near a mosque, you will probably hear a person calling out in Arabic. This is the call-to-prayer, which is why mosques have large towers.
Many Muslims pray five times a day.
Once a year, Muslims fast (go without food or water) for a month during the daytime, meaning that they cannot eat or drink from when the sun rises until when the sun sets. The celebration at the end of Ramadan is called Eid-ul-Fitr.
Hajj pilgrimage is an annual pilgrimage to Mecca which is the Islam holy city. It is strictly compulsory for those Muslims who can physically and financially afford to go there. They also need to be able to support their family in their absence.
