عَنْ أَبِي قِلَابَةَ قَالَ قَدِمَ هِشَامُ بْنُ عَامِرٍ الْبَصْرَةَ فَوَجَدَهُمْ يَتَبَايَعُونَ الذَّهَبَ فَقَامَ فَقَالَ إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَهَى عَنْ بَيْعِ الذَّهَبِ بِالْوَرِقِ نَسِيئَةً وَأَخْبَرَ أَنَّ ذَلِكَ هُوَ الرِّبَا
It is narrated from Abu Qalabah that Sayyiduna Hisham bin ‘Amir (may Allah be pleased with him) came to Basra and saw that people there were buying gold in exchange for silver on credit. So he stood up and said that the Messenger of Allah (peace and blessings be upon him) forbade selling gold for silver on credit, and also said that this is usury.
