Al-Qasim bin Muhammad narrates from Sayyidah Aishah (may Allah be pleased with her) that a male slave and a female slave of Sayyidah Aishah (may Allah be pleased with her) were husband and wife. Sayyidah Aishah (may Allah be pleased with her) said: "O Messenger of Allah! I want to set them free." He (peace and blessings be upon him) said: "If you intend to set them free, then free the man first, and free the woman afterwards."
Ibn Mawhab, who is Ubaydullah bin Abd al-Rahman bin Mawhab, is alone in narrating it.
