رُوِيَ عَنْ عَمَّارٍ السَّابَاطِيِّ عَنْ أَبِي عَبْدِ اللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ قُلْتُ لَهُ الرَّجُلُ يَبِيعُ الدَّرَاهِمَ بِالدَّنَانِيرِ نَسِيئَةً قَالَ لَا بَأْسَ بِهِ.
It is narrated from Ammar al-Sabati, from Abu Abdullah عليه السلام, who said: I asked him about a man who sells dirhams for dinars on credit. Imam عليه السلام said: "There is no harm in it."
