Chapter on Freedom
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 1|Chapter 51
وَ رَوَى هِشَامُ بْنُ سَالِمٍ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: "قَضَى أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ فِيمَنْ نَكَّلَ بِمَمْلُوكِهِ أَنَّهُ حُرٌّ لاَ سَبِيلَ لَهُ عَلَيْهِ سَائِبَةٌ يَذْهَبُ فَيَتَوَلَّى إِلَى مَنْ أَحَبَّ فَإِذَا ضَمِنَ حَدَثَهُ فَهُوَ يَرِثُهُ".
Hisham ibn Salim narrated from Abu Basir, from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام: "Commander of the Faithful, peace be upon him, ruled regarding a person who mistreated his slave that the slave becomes free. There is no authority over him, and he is considered a 'sa'ibah' (free without obligation). He may choose to align himself with whomever he wishes, and if that person guarantees his liability, then he inherits from him."
