bayhaqi:13733Ibn ʿUmar > Kān

[Machine] He used to say that if he marries without the permission of his guardians, divorce is in the hands of the servant. It has been narrated from Umar ibn Al-Khattab, in the same sense, and from Ibn Umar, that he said about a slave who married a free woman without the permission of his guardians: she has made her private part permissible.
