Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 1|Chapter 50
وَ رَوَى اِبْنُ مُسْكَانَ عَنْ سُلَيْمَانَ بْنِ خَالِدٍ عَنْ بَعْضِهِمْ عَلَيْهِمُ اَلسَّلاَمُ قَالَ: "كَانَ عَلِيٌّ عَلَيْهِ اَلسَّلاَمُ إِذَا مَاتَ اَلرَّجُلُ وَ لَهُ اِمْرَأَةٌ مَمْلُوكَةٌ اِشْتَرَاهَا مِنْ مَالِهِ فَأَعْتَقَهَا ثُمَّ وَرَّثَهَا".
Ibn Muskan narrated from Sulaiman ibn Khalid, who narrated from some of the Imams عليه السلام, peace be upon them: "When a man died and had a wife who was a slave, Imam Ali ibn Abi Talib عليه السلام would purchase her from his estate, emancipate her, and then make her an heir."
