Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 11
وَ رَوَى اَلْحَلَبِيُّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: أَنَّهُ سُئِلَ عَنْ رَجُلٍ اِشْتَرَى جَارِيَةً بِثَمَنٍ مُسَمًّى ثُمَّ بَاعَهَا فَرَبِحَ فِيهَا قَبْلَ أَنْ يَنْقُدَ صَاحِبَهَا اَلَّذِي كَانَتْ لَهُ فَأَتَى صَاحِبُهَا يَتَقَاضَاهُ فَقَالَ صَاحِبُ اَلْجَارِيَةِ لِلَّذِينَ بَاعَهُمْ اِكْفُونِي غَرِيمِي هَذَا وَ اَلَّذِي رَبِحْتُ عَلَيْكُمْ فَهُوَ لَكُمْ فَقَالَ "لاَ بَأْسَ".
Al-Halabi narrated from Abu Abdullah عليه السلام that he was asked about a man who bought a bondwoman for a specified price, then sold her and made a profit before paying the original seller. The original seller came to demand his payment, so the man who sold the bondwoman said to those who bought her: "Take care of this creditor of mine, and the profit I made from you is yours." Imam عليه السلام said: "There is no harm in this."
