Maria the Copt (Mariyah Al-Qibtiyyah)
Mariya Al-Qibtiya was one of the concubines/sex slaves of the prophet Muhammad. According to the sira she was sent to Muhammad as a gift from the Christians of Egypt. According to the hadith and the sirah her beauty incited the jealousy of Muhammad's wives, in particular Hafsa and Aisha. The jealousy they had of her and Muhammad's response was actually the cause of the "revelation" of some Qur'an verses according to the tradition. Although she bore the prophet a son who later died, the prophet never married her. The traditional sources compare her concubinage to that of Hajar to Ibrahim, based upon the fact that, according to the tradition, the closest person to Muhammad was the prophet Ibrahim. According to classical Islamic sources, had her son Ibrahim lived, he too would have been a prophet.
Life Before Muhammad
Not much is known of Mariyah's life before she was gifted to the prophet as a sex slave. According to the traditional sources, she was the son of a certain Scham'un from the town of Hafn in the region of Ansina. According to the traditional sources, she was gifted to Muhammad with her sister; but since the shari'ah prohibits a man having sexual relations with a woman and her sister, Muhammad was forced to choose between the two, and choose Mariya for her exceeding beauty.
Gifting to Muhammad and Conversion to Islam
According to the traditional sources, after the treaty of Hudaybiya, the prophet Muhammad sent letters to the heads of various Middle Eastern powers inviting them to convert to Islam. One of these letters went to a certain Muhammad Al-Maqauqis, who is not immediately identifiable with any historical person but is identified by later sources as the Patriarch Cyril of Egypt. He did not, apparently, accept the call to Islam but in response sent Mariyah and his sister as sex slaves to Muhammad. That a Christian patriarch in Egypt would send Christian girls as sex slaves to this strange, obscure, and previously unknown heretic in Arabia was a question that apparently never arose on any side. On the way to Medina, she converted to Islam. When she and her sister arrived in Medina, since Muhammad could not have concurrent sexual relations with both sisters as per Islamic law, Muhammad chose Mariyah for her exceeding beauty. The prophet did not wed her, but rather kept her as his jarriyah or sirriyah, that is his sex slave.
