Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 11
وَ رَوَى عَاصِمُ بْنُ حُمَيْدٍ عَنْ أَبِي بَصِيرٍ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلرَّجُلِ يَقُولُ لِلرَّجُلِ أَبْتَاعُ لَكَ مَتَاعاً وَ اَلرِّبْحُ بَيْنِي وَ بَيْنَكَ قَالَ "لاَ بَأْسَ بِهِ".
Asim bin Humayd narrated from Abu Basir: I asked Abu Abdullah عليه السلام about a man who says to another man, "I will buy merchandise for you, and the profit will be shared between me and you." Imam عليه السلام said: "There is no harm in it."
