[Machine] The Messenger of Allah ﷺ said, "Indeed, riba (usury) is only in debt." Abdullah said, "Its meaning is one dirham exchanged for two dirhams."  

الدارمي:٢٦٢٢أَخْبَرَنَا أَبُو عَاصِمٍ عَنْ ابْنِ جُرَيْجٍ عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي يَزِيدَ عَنْ ابْنِ عَبَّاسٍ قَالَ أَخْبَرَنِي أُسَامَةُ بْنُ زَيْدٍ

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «إِنَّمَا الرِّبَا فِي الدَّيْنِ» قَالَ عَبْد اللَّهِ «مَعْنَاهُ دِرْهَمٌ بِدِرْهَمَيْنِ»

"Dinar for Dinar Dirham for Dirham, no difference between them." (Using translation from Nasāʾī 4567)  

ابن حبّان:٥٠١٢أَخْبَرَنَا عُمَرُ بْنُ سَعِيدِ بْنِ سِنَانٍ بِمَنْبِجَ قَالَ أَخْبَرَنَا أَحْمَدُ بْنُ أَبِي بَكْرٍ عَنْ مَالِكٍ عَنْ مُوسَى بْنِ أَبِي تَمِيمٍ عَنْ سَعِيدِ بْنِ يَسَارٍ عَنْ أَبِي هُرَيْرَةَ

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «الدِّينَارُ بِالدِّينَارِ وَالدِّرْهَمُ بِالدِّرْهَمِ لَا فَضْلَ بَيْنَهُمَا»
