Two slave girls whom the Messenger of Allah, may Allah bless him and grant him peace, married. Who are they?

The Prophet, peace and blessings be upon him, did not marry two slave girls while they were still in a state of slavery. Rather, he married free women who had previously been enslaved and then emancipated them. These were: Juwayriyyah bint Al-Harith and Safiyyah bint Huyayy. As for his female slaves with whom he cohabited through ownership by the right hand, it is said there were four: Mariyah al-Qibtiyyah, Rayhanah from Banu Qurayzah, a third slave girl from the captives, and a slave girl gifted to him by Zaynab bint Jahsh.
