Ibn Mālik, Abū ʻAbd Allāh Djamāl Al-Dīn Muhammad (Arabic: ابن مالك، محمد بن عبد الله‎) (c. 600 AH - 672 AH / c. 1204 - 22 February 1274) was an Arab grammarian born in Jaén, Spain. After leaving Spain for the Near East, he became a Shāfi‘ī, and taught Arabic language and literature in Aleppo and Hamāt, before eventually settled in Damascus, where he began the most productive period of his life. He was a senior master at the Adiliyya Madrasa. His reputation in Arabic literature was cemented by his al-Khulāsa al-alfiyya (known also as simply Alfiya), a versification of Arabic grammar, for which at least 43 commentaries have been written.

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.
