Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 11
وَ رُوِيَ عَنْ مُحَمَّدِ بْنِ قَيْسٍ قَالَ: قُلْتُ لِأَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ رَجُلٌ دَفَعَ إِلَى رَجُلٍ أَلْفَ دِرْهَمٍ مُضَارَبَةً فَاشْتَرَى أَبَاهُ وَ هُوَ لاَ يَعْلَمُ قَالَ "يُقَوَّمُ فَإِنْ زَادَ دِرْهَماً وَاحِداً أُعْتِقَ وَ اُسْتُسْعِيَ فِي مَالِ اَلرَّجُلِ ".
It is narrated from Muhammad bin Qays who said: I said to Abu Abdillah عليه السلام, "A man gave another man one thousand dirhams in a partnership, and he unknowingly purchased his father with it." Imam عليه السلام said: "He should be valued, and if his value exceeds by even one dirham, he shall be freed and shall work to repay the man's wealth."
