[Machine] Abu Muslim al-Kashi and Yusuf al-Qadi narrated to us, they said: Suleiman bin Harb said: Hammad bin Zaid narrated to us from Ayyub from Abu Qilabah who said: Hisham bin Amer came to Basra and found them trading gold with their credit. So he stood and said, "The Messenger of Allah ﷺ forbade the exchange of gold for credit, as it is a form of usury." And the wording is from Suleiman bin Harb.  

وَحَدَّثَنَا أَبُو مُسْلِمٍ الْكَشِّيُّ ويُوسُفُ الْقَاضِي قَالَا ثنا سُلَيْمَانُ بْنُ حَرْبٍ قَالَا ثنا حَمَّادُ بْنُ زَيْدٍ عَنْ أَيُّوبَ عَنْ أَبِي قِلَابَةَ قَالَ قَدِمَ هِشَامُ بْنُ عَامِرٍ الْبَصْرَةَ فَوَجَدَهُمْ يَتَبَايَعُونَ الذَّهَبَ فِي أُعْطِيَاتِهِمْ فَقَامَ فَقَالَ «نَهَى رَسُولُ اللهِ ﷺ عَنْ بَيْعِ الذَّهَبِ بِالْوَرِقِ نَسِيئَةً وَأَخْبَرَنَا أَنَّ ذَلِكَ هُوَ الرِّبَا» وَاللَّفْظُ لِسُلَيْمَانَ بْنِ حَرْبٍ
