It is narrated from Hazrat Bakr bin Abdullah Al-Muzani (may Allah have mercy on him): A woman was brought to Sayyiduna Umar bin Khattab (may Allah be pleased with him) who had married her slave. He was strict with her and wrote to the cities that a woman should not marry her slave or marry without a guardian, otherwise she should be punished.
