[Machine] I heard Abu Qilabah say that during the time of Ibn Ziyad, people used to exchange dinars for dirhams in an unjust manner. So a man from the companions of the Prophet ﷺ , named Hisham ibn 'Ammar, stood up and said, "Indeed, the Messenger of Allah ﷺ prohibited the sale of gold for paper currency in an unjust manner, and he informed us that it is a form of usury."
سَمِعْتُ أَبَا قِلَابَةَ وَكَانَ النَّاسُ زَمَنَ ابْنِ زِيَادٍ يَأْخُذُونَ الدَّنَانِيرَ بِالدَّرَاهِمِ نَسِيئَةً فَقَامَ رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ ﷺ يُقَالُ لَهُ هِشَامُ بْنُ عَامِرٍ فَقَالَ «إِنَّ رَسُولَ اللهِ ﷺ نَهَى عَنْ بَيْعِ الذَّهَبِ بِالْوَرِقِ نَسِيئَةً وَأَنْبَأَنَا أَنَّ ذَلِكَ مِنَ الرِّبَا»
