"Ubadah bin As-Samit and Muawiyah met at a stopping place on the road. 'Ubadah told them: 'The Messenger of Allah forbade selling gold for gold, silver for silver, wheat for wheat, barley for barley, dates for dates"'- one of them said: 'salt for salt,"' but the other did not say it-"unless it was like for like, hand to hand. And he commanded us to sell gold for silver and silver for gold, and wheat for barley and barley for wheat, and to hand, however we wanted."' And one of them said: "Whoever gives more or ask for more has engaged in Riba."' (Using translation from Nasāʾī 4560)  

نَهَى رَسُولُ اللهِ ﷺ عَنْ بَيْعِ الذَّهَبِ بِالذَّهَبِ وَالْوَرِقِ بِالْوَرِقِ وَالْبُرِّ بِالْبُرِّ وَالشَّعِيرِ بِالشَّعِيرِ وَالتَّمْرِ بِالتَّمْرِ قَالَ أَحَدُهُمَا وَالْمِلْحِ بِالْمِلْحِ وَلَمْ يَقُلْهُ الْآخَرُ إِلَّا مِثْلًا بِمِثْلٍ يَدًا بَيْدٍ وَأَمَرَنَا أَنْ نَبِيعَ الذَّهَبَ بِالْوَرِقِ وَالْوَرِقَ بِالذَّهَبِ وَالْبُرَّ بِالشَّعِيرِ وَالشَّعِيرَ بِالْبُرِّ يَدًا بَيْدٍ كَيْفَ شِئْنَا قَالَ أَحَدُهُمَا فَمَنْ زَادَ أَوِ ازْدَادَ فَقَدْ أَرْبَى

One of them said: "Whoever gives more or takes more has engaged in Riba," but he other one did not say it. "And he commanded us to sell gold for silver and silver for gold, and wheat for barley and barley for wheat, hand to hand, however we wanted." (Using translation from Nasāʾī 4561)  

نَهَانَا رَسُولُ اللهِ ﷺ عَنْ الذَّهَبِ بِالذَّهَبِ وَالْفِضَّةِ بِالْفِضَّةِ وَالتَّمْرِ بِالتَّمْرِ وَالْبُرِّ بِالْبُرِّ وَالشَّعِيرِ بِالشَّعِيرِ قَالَ أَحَدُهُمَا وَالْمِلْحِ بِالْمِلْحِ وَلَمْ يَقُلْهُ الْآخَرُ إِلَّا سَوَاءً بِسَوَاءٍ مِثْلًا بِمِثْلٍ قَالَ أَحَدُهُمَا مَنْ زَادَ أَوِ ازْدَادَ فَقَدْ أَرْبَى وَلَمْ يَقُلِ الْآخَرُ وَأُمِرْنَا أَنْ نَبِيعَ الذَّهَبَ بِالْفِضَّةِ وَالْفِضَّةَ بِالذَّهَبِ وَالْبُرَّ بِالشَّعِيرِ وَالشَّعِيرَ بِالْبُرِّ يَدًا بَيْدٍ كَيْفَ شِئْنَا
