Sheikh is an Arabic honorific title awarded to the patriarch of a tribe. The said title is inherited from ancestors. Sheiks are like kings in the Western world. They are the ones who govern their countries, which are mostly located in the Middle East. Most of the sheiks are members of the royal family in Arabian Peninsula. Sheikhs are categorized into two types - the Islamic scholar and the Islamic Sufism. As scholars, they need to attain a degree in Hadith, Tafseer, and Fiqh from any University of Islamic Sciences or Jamia. In Islamic Sufism, which is also known as the inward dimension of Islam, these sheikhs are authorized to teach, initiate, and guide aspiring dervishes in the Islamic faith. But how do these sheikhs actually manage to build their fortune? Basically, they gain profits from the oil and gas enterprises in their countries. They are known to live a life of luxury. They often engage in tremendous adventures. They are also keen of traveling around the world and some have even acquired a playboy reputation. Despite their luxurious lifestyles, many sheikhs are known to be involved in philanthropic activities. They dole out money for the less fortunate people and numerous charitable institutions. Some of these sheikhs have slowed down their public life, but there are others who decided to focus on government positions and royal duties.
