Mos Def is set to change his name by the end of the year and will call himself Yasiin.

"I'm actually doing it, I'm retiring the name Mos Def after 2011" he told "Mos Def is a name that I built and cultivated over the years, it's a name that the streets taught me, a figure of speech that was given to me by the culture and by my environment, and I feel I've done quite a bit with that name. [But] it's time to expand and move on." Born Dante Smith, the rapper converted to Islam in his teens and has taken his new name from his religion as Yasiin is a name in the Qur'an 36th surah.
