Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 1|Chapter 49
وَ رَوَى اِبْنُ مَحْبُوبٍ عَنْ عَمَّارِ بْنِ أَبِي اَلْأَحْوَصِ قَالَ: سَأَلْتُ أَبَا جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلسَّائِبَةِ قَالَ "اُنْظُرْ فِي اَلْقُرْآنِ فَمَا كَانَ فِيهِ تَحْرِيرُ رَقَبَةٍ فَذَلِكَ يَا عَمَّارُ اَلسَّائِبَةُ اَلَّتِي لاَ وَلاَءَ لِأَحَدٍ مِنَ اَلْمُسْلِمِينَ عَلَيْهِ إِلاَّ اَللَّهَ عَزَّ وَ جَلَّ فَمَا كَانَ وَلاَؤُهُ لِلَّهِ عَزَّ وَ جَلَّ فَهُوَ لِرَسُولِهِ وَ مَا كَانَ لِرَسُولِهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ فَإِنَّ وَلاَءَهُ لِلْإِمَامِ وَ جِنَايَتَهُ عَلَى اَلْإِمَامِ وَ مِيرَاثَهُ لَهُ".
Ibn Mahbub narrated from Ammar ibn Abi Al-Ahwas, who said: I asked Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام, about al-sa'ibah (a freed slave without specific ties). Imam عليه السلام said: "Look in the Qur'an. Wherever there is mention of the freeing of a slave, that, O Ammar, refers to the sa'ibah, who has no wala' (loyalty) to any Muslim except Allah سبحانه وتعالى, the Mighty and Majestic. So, whoever's wala' belongs to Allah سبحانه وتعالى, it belongs to His Messenger. And whatever belongs to His Messenger, peace and blessings be upon him and his family, its wala' belongs to the Imam. His liabilities (for crimes or debts) are upon the Imam, and his inheritance belongs to the Imam."
