Islamic places of worship are called mosques. A mosque is not only a place of worship but a center for the Muslim community. It is also a key place for intellectual and social activities.
There are several rules involved with entering or worshipping inside a mosque. When entering the prayer hall, whether to worship or visit, a person must be clean and remove their shoes. The no-shoes rule may be extended to other parts of the mosque even if they are sections that are not included in the worship services. It is also frowned upon to enter the prayer hall after eating something that smells strongly like garlic.
Mosques come in many different shapes and sizes depending on the region in which they are located. Muslims of the past and present have used local architects and artisans to create magnificent, unique mosques. There is one detail that all mosques have in common, and that is the mihrab, which is a niche in a wall that points in the direction of Mecca, Saudi Arabia. This is the direction that Muslims face when praying to God, or Allah.
