"Mohammed had many male and female slaves. He used to buy and sell them, but he purchased more slaves than he sold, especially after God empowered him by His message, as well as after his immigration from Mecca.

He was used to renting out and hiring many slaves, but he hired more slaves than he rented out." - Ibn Qayyim al-Jawziyya
