يوسف بن تاشفين
Yusuf ibn Tashfin was a Berber from the Banu Turgut, a branch of the Lamtuna, a Tuareg tribe belonging to the Sanhaja group. The Sanhaja were linked by medieval Muslim genealogists with the Yemeni tribe of Himyar through semi-mythical and mythical pre-Islamic kings and for some reason, some of the contemporary sources (e.g., Ibn al-Arabi) add the "nisba" al-Himyari to Yusuf's name to indicate this legendary affiliation. Modern scholarship rejects this Berber–Yemeni link as fanciful.
