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 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 albums, the Ummah provided backing tracks and remixes for a notable array of hip hop and contemporary R&B artists, including Busta Rhymes, Whitney Houston, Keith Murray, the Brand New Heavies, Michael Jackson, Janet Jackson, and Jon B. The group was so named because two of its members are devout Muslims. The word "ummah" is Arabic for "community", "nation", or "brotherhood". Generally, the term refers to the global Muslim population.
