bayhaqi:13995Abū Saʿīd > Abū al-ʿAbbās > al-Rabīʿ > al-Shāfiʿī > ʿAbd al-Majīd > Ibn Jurayj > Ibn Ṭāwus from his father

[Machine] Abu al-Abbas reported that Rabi'a reported that Shafi'i reported that Abdul-Majid reported from Ibn Jurayj, who narrated to me that Ibn Tawus told me, on the authority of his father, who said: "The marriage of a free man to a female slave, while he already has a free woman as a wife, is not permissible." I said: "Is it because of the fear of adultery?" He said: "I do not know if that is the reason."
