رَوَى يُونُسُ بْنُ عَبْدِ الرَّحْمَنِ عَنْ غَيْرِ وَاحِدٍ عَنْ أَبِي عَبْدِ اللَّهِ عَلَيْهِ اَلسَّلاَمُ فِي الرَّجُلِ يُبَايِعُ الرَّجُلَ عَلَى الشَّيْءِ فَقَالَ لَا بَأْسَ إِذَا كَانَ أَصْلُ الشَّيْءِ حَلَالًا.
Yunus ibn Abd al-Rahman narrated from more than one person, from Abu Abdullah (a.s), regarding a man who trades with another man over something. Imam (a.s) said: "There is no harm, as long as the origin of the item is lawful."
