Abdul Aziz (Arabic: عبد العزيز‎) is a male Muslim given name and in modern usage, surname. It is built from the Arabic words Abd, al- and Aziz. The name means "servant of the Almighty", Al-Azīz being one of the names of God in the Qur'an, which give rise to the Muslim theophoric names.

The letter a of the al- is unstressed, and can be transliterated by almost any vowel, often by u. So the first part can appear as Abdel, Abdul or Abd-al. The second part may appear as Aziz or Azeez, or in other ways. The whole name is subject to variable spacing and hyphenation.

King Abdul-Aziz of Saudi Arabia (1876 – 9 November 1953) (Arabic: عبد العزيز آل سعود‎ ‘Abd al-‘Azīz Āl Su‘ūd) was the first monarch of Saudi Arabia, the third Saudi State. He was usually called Ibn Saud in English-speaking countries.

Beginning with the reconquest of his family's ancestral home city of Riyadh in 1902, he consolidated his control over the Najd in 1922, then conquered the Hijaz in 1925. Having conquered almost all of central Arabia, he united his dominions into the Kingdom of Saudi Arabia in 1932. As King, he presided over the discovery of petroleum in Saudi Arabia in 1938 and the beginning of large-scale oil exploitation after World War II. He was the father of many children having 45 sons, including all of the subsequent kings of Saudi Arabia.

Abdul-Aziz was born in 1876 in Riyadh, in the region of Najd in central Arabia.

In 1890, the Al Rashid conquered Riyadh. Abdul-Aziz was 15 at the time. He and his family initially took refuge with the Al-Murrah, a Bedouin tribe in the southern desert of Saudi Arabia. Later, the Al Sauds moved to Kuwait.

Fethullah Gülen (born 27 April 1941) is a Turkish author, educator, and Muslim scholar. Gülen has been described in the English-language media as "one of the world's most important Muslim figures." He is the founder of the Gülen movement. He currently lives in self-imposed exile in Pennsylvania, USA.

Gülen teaches an Anatolian version of Islam, deriving from Sunni Muslim scholar Bediüzzaman Said Nursi's teachings and modernizing them. Gülen has stated his belief in science, interfaith dialogue among the People of the Book, and multi-party democracy. He has initiated such dialogue with the Vatican and some Jewish organizations.

Gülen is actively involved in the societal debate concerning the future of the Turkish state, and Islam in the modern world. In the Turkish context Gülen appears relatively conservative and religiously observant.

His role in Turkish politics is a controversial one, and in 1999 he was put on trial for attempting to overthrow the government. He has since lived in exile in the United States. He was acquitted of the charges in 2008. He has been seen as supportive of Turkey's current prime minister Recep Tayyip Erdogan, but news emerging in May 2012 emerged of a possible conflict between the two.

Abdul Aziz was born in 1973. His mother wanted to be called Umm 'Abd al-'Aziz (mother of 'Abd al-'Aziz).

In fact, his mother is al Jawhara bint Ibrahim al Ibrahim, belonging to the wealthy al Ibrahim family. Her sister, Maha al Ibrahim, is married to former deputy minister of Defence and Aviation, Prince Abdul Rahman. His another sister, Mohdi al Ibrahim, is married to minister of Higher Education, , Dr. Khaled Al Anqari.

Al Jawhara al Ibrahim divorced from her first husband to wed King Fahd. Al Jawhara's place at his side provided her brothers with the opportunity to become influential businessmen, leading to jealousy and gossip in royal circles.

The fact that she travelled with King Abdallah to Kuwait in January 2007 to pay the family's respects upon the death of the Amir Jabir al Ahmad al Sabah is considered to be a sign of her continuing influence.
