evidence: Saudi Arabia,[b] officially known as the Kingdom of Saudi Arabia (KSA),[c] is a country in West Asia including most of the Arabian Peninsula. The land area is approximately 2,150,000 km2 (830,000 sq mi), so Saudi Arabia is geographically the 5th-largest state in Asia and 2nd-largest state in the Arab world after Algeria. Saudi Arabia is bordered by Jordan and Iraq to the north, Kuwait to the northeast, Qatar, Bahrain, and the United Arab Emirates to the east, Oman to the southeast, and Yemen to the south. It is separated from Palestine and Egypt by The Red sea. It is the only nation with both a Red Sea coast and the Arabian Gulf coast, and most of its land is dry and barren. Saudi Arabia is the birthplace of Arabs and Islam [9] and sometimes called "the Land of the Two Holy Mosques" in reference to Al-Masjid al-Haram (in Mecca), and Al-Masjid an-Nabawi (in Medina), the two holiest places in Islam. Arabic is the exclusive official language in Saudi Arabia. [...] The countries of Yemen and Oman are south of Saudi Arabia. Saudi Arabia is west of Qatar, the United Arab Emirates, Kuwait, Iraq, and Jordan. All of these countries, except Jordan and Iraq, make the Arabian Peninsula.
