The Importance of Respect in Islam

All slaves are from inferior classes, you cannot enslave your own. Islam demolished this whole jahiliya of having caste systems based upon one's lineage and based on skin color. Al Khabab even, Arat was one of the Arab slaves, and his master actually was female, not male,. And Ume-an-mar purchased Khabab because he was a sword maker. He would hammer out swords for the people of Mecca.
