Chapter on the Divorce by a Slave
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 4|Chapter 20
وَ رَوَى اَلْعَلاَءُ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا عَلَيْهِمَا اَلسَّلاَمُ قَالَ: "طَلاَقُ اَلْأَمَةِ بَيْعُهَا أَوْ بَيْعُ زَوْجِهَا" وَ قَالَ فِي اَلرَّجُلِ يُزَوِّجُ أَمَتَهُ رَجُلاً حُرّاً ثُمَّ يَبِيعُهَا قَالَ "هُوَ فِرَاقُ مَا بَيْنَهُمَا إِلاَّ أَنْ يَشَاءَ اَلْمُشْتَرِي أَنْ يَدَعَهُمَا".
Al-ʿAlaʾ narrated from Muḥammad ibn Muslim from one of the two Imams (peace be upon them), who said: "The divorce of a bondwoman is through her sale or the sale of her husband." Imam عليه السلام also said regarding a man who marries his bondwoman to a free man and then sells her: "This constitutes separation between them unless the buyer wishes to let them remain together."
