- Requires the Mosque Worship Belief to be constructed.
The Mosque can help speed up the spread of your religion, making it very useful when pursuing a Religious Victory. The main advantage of it is that you only really need one. That makes it a much cheaper investment than all the other religious buildings (which are frankly expensive for what you get), though later in the game you may want to dot a few more around the globe.
There are strict requirements and standards in Islamic fiqh for a building to be a mosque, and those places of worship that do not meet those are merely musallas (“gathering houses”). Under Sharia law, once a mosque is formally designated as a holy place, it remains that until the Day of Judgment (Yawm ad-Din). The oldest and largest mosque in the world, the Masjid al-Haram, was built in the city of Mecca around 638 AD; it encompasses the holy site of the Kaaba, the most sacred of all locations in Islam. The Prophet himself established other mosques, notably that at Medina. From there, mosques – with their distinctive domes, minarets and prayer halls overseen by an imam – were carried by the swords of the faithful across Arabia, the Middle East and North Africa during the 7th Century. The first mosque built in the Far East – that at Xi’an – reportedly dates to the mid-8th Century. A site of prayer, charity and learning, the mosque is the physical heart of Islamic civilization.
