Article 2 of the Constitution states, "The religion of the State is Islam, and the Islamic Sharia shall be one of the main source of legislation." The vast majority of Kuwaitis are Muslim. Article 35 of the Constitution states that "Freedom of belief is absolute. The State protects the freedom of practicing religion in accordance with established customs, provided that it does not conflict with public policy or morals." The Ministry of Awqaf and Islamic Affairs has the responsibility of maintaining the spiritual and religious aspects and preserve the Islamic heritage.
The Language
Arabic is the official language of the State of Kuwait and all documents and notices are in modern standard Arabic. Most correspondence with government departments must be in Arabic and most official forms must be filled-out in Arabic. In the oil sector however the lingua franca in is English.
Private businesses are generally free to use whatever language they wish in contracts, correspondence and notices. A few types of contracts however, such as regulation posted in a place of work, are required by law to be in Arabic though a translation in another language may be appended. Where a document is in more than one language, the Arabic version is always authoritative.
English is considered the second language of business and many educated Kuwaitis are fluent English speakers. Getting by on English alone can sometimes prove difficult.
