Hadith 10:543
Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: Yunus bin Abi Ishaq narrated to us, from his father, from Mus’ab bin Sa’d: That Sa’d married a slave girl of his to a slave of his, then his soul followed her (i.e., he desired her). He said: So he made a condition upon his slave that he must divorce her.
حدثنا أبو بكر قال نا وكيع قال نا يونس بن أبي إسحاق عن أبيه عن مصعب بن سعد أن سعدا زوج جارية له مملوكا له فتبعتها نفسه قال فجعل لغلامه حقا على أن يطلقها
