Maria al-Qibtiyya (Arabic: ?) (alternatively, "Maria Qupthiya"), or Maria the Copt, (died 637) was an Egyptian Coptic Christian (who turned into a Muslim wife of the prophet according to Sunni Islam) slave who was sent as a gift from Muqawqis, a Byzantine official, to the Islamic prophet Muhammad in 628. According to some Islamic accounts, she was Muhammad's wife, and therefore a "Mother of the Believers" (Arabic: Ummahat-al-Mu'mineen), other sources such as Ibn Qayyim Al-Jawziyya talk about her being only a concubine. She was the mother of Muhammad's son Ibrahim, who died in infancy. Her sister, Sirin, was also sent to Muhammad. Muhammad gave her to his follower Hassan ibn Thabit. Maria never remarried after Muhammad's death in 632, and died five years later. Her birthdate is unknown. No primary source mentions her age.
