Abdul Rahman Saleem, (born Rahman Yahyaei) also known as Abu Yahya, is a British-Iranian Islamic activist, born around 1975.

Saleem was born in Mashhad, Iran in 1975 to a Punjabi Sunni family. He left Iran for London in 1979 following the Iranian Revolution where he was bullied and discriminated against for his Asian identity. This provoked his embracement of radical Islam and later he became closely acquainted with Al-Muhajiroun members Omar Bakri and Anjem Choudary. Nonetheless, he excelled in his studies, earning 11 A* Grades at GCSE and 5 A grades at A Level in English literature, Persian, Further Mathematics, Mathematics and Physics. Despite this, he opted to attend University in Iran and was granted a placement at Sharif University of Technology to study Mechanical Engineering in 1993. He graduated in 1998 and returned to the United Kingdom the following year.

He is a former Al Muhajiroun spokesman, a former member of the Saved Sect, and was a prominent member of al-Maddad, an organization that claims to have sent dozens of British Muslims to fight in Chechnya and elsewhere. In August 2001, ...he went to secret camps in Pakistan and Afghanistan and trained in the use of guns and explosives.

Abdur Rahman (Arabic: عبد الرحمن‎ or occasionally عبد الرحمان) is a male Muslim given name, and in modern usage, surname. It is built from the Arabic words Abd, al- and Rahman. The name means "servant of the most gracious", ar-Rahman 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. Because the letter r is a sun letter, the letter l of the al- is assimilated to it. Thus although the name is written in Arabic with letters corresponding to Abd al-Rahman, the usual pronunciation corresponds to Abd ar-Rahman. Alternative transliterations include ‘Abd ar-Rahman, Abdul Rahman, Abdur Rehman, Abdul Rehman, Abidur Rahman, and others, all subject to variant spacing and hyphenation. Certain transliterations tend to be associated with certain areas, for example, Abdirahman in Somalia, and Abderrahmane in French-speaking North Africa.

The Ummah was a music production collective, composed of members Q-Tip and Ali Shaheed Muhammad of A Tribe Called Quest, and the late Jay Dee (now known as J Dilla) of the Detroit-based group Slum Village. Occasional members included Raphael Saadiq, and D'Angelo. In addition to producing nearly the entirety of A Tribe Called Quest's fourth and fifth album, the Ummah provided backing tracks for a notable array of hip hop and contemporary R&B artists, including Busta Rhymes, Whitney Houston, Keith Murray, the Brand New Heavies, Janet Jackson, and Jon B. The group was so named because two of its members (Tip and Ali) are devout Muslims. The word "ummah" is Arabic for "community", "nation", or "brotherhood".

The collective took shape around 1995, when veteran keyboardist Amp Fiddler introduced Jay Dee (who at the time was shopping for a deal for his group) to Q-Tip. Tip was impressed enough by Jay Dee's soulful productions to invite him as an addition to Tribe's music-production team, which until then consisted of Tip and Ali Shaheed.
