I really dont understand why certain people believe that Islam promoted slavery?! Islam just gave equal rights yo these arab culture is one of the dirtiest cultures.
Islam gave slaves a new name ,a new status and a new identity! Islam uses the word "what your right hand possess" in Arabic we say "ma malikatum aymanukum " Allah almighty will severely punish us Muslims if we miss treat concubines therefore we built servant quarters to give rights to concubines
Peace,!
