Among the Signs of the Hour is that a slave woman gives birth to her mistress

Question: It came in a hadith from the Messenger of Allah (peace and blessings be upon him), narrated by 'Umar ibn al-Khattab (may Allah be pleased with him) : "That among the signs of the Hour is that a slave woman gives birth to her mistress." I ask your eminence to explain and clarify the meaning of a slave woman giving birth to her mistress?

Answer: The meaning is: that among the signs of the Hour is that concubines become numerous among people, until a slave woman gives birth to her mistress; that is, she becomes pregnant by her master and gives birth to her mistress; because the daughter of a master is a mistress and the son of a master is a master. May Allah help us.
