HOLIEST PLACE ON THE EARTH
As the birthplace of Muhammad and a site of the revelation of the Quran,[4][5] Mecca is regarded as the holiest city in the religion of Islam[6] and a pilgrimage to it known as the Hajj is obligatory for all able Muslims. Mecca was long ruled by Muhammad's descendants, the sharifs, either as independent rulers or as vassals to larger empires. It was absorbed into Saudi Arabia in 1925. In its modern period, Mecca has seen tremendous expansion in size and infrastructure. Because of this, Mecca has lost many thousand-year-old buildings and archaeological sites.[7] Today, more than 15 million Muslims visit Mecca annually, including several million during the few days of the Hajj.[8] As a result, Mecca has become one of the most cosmopolitan and diverse cities in the Muslim world,[9] although non-Muslims are prohibited from entering the city.[10][11] <
Location Of Makkah
Makkah is at the intersection of latitude 21 to 25 degree north and longitude 39 to 49 degree east. It is set in a rugged landscape consisting mostly of solid granite, with rocks sometimes reaching 300 meters (1,000 feet) above see level.
Makkah is enclosed by the Valley of Abraham, which is surrounded by two nearby mountain ranges to the east, west and south. The northern range comprises the Al-Falaq and Qu'aqi'an mountains, while the southern range consists of Abu Hudaidah mountain to the west, Kuday to the south and Abu Qubais and Khindimah to the south-east.
There are three main entrances to Makkah: Al-Mu'allat (also known as Al-Hujûn), Al-Musfalah and Al-Shubaikah.
It is generally agreed that Al-Mu'allat includes all areas which are higher than the Haram and Al-Musfalah covers all areas that are lowers.
