"Ubadah bin As-Samit and Muawiyah met at a stopping place on the road. 'Ubadah said: 'The Messenger of Allah forbade us to sell 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 "unless it was equal amount for equal amount, like for like." One of them said: "Whoever gives more or takes more has engaged in Riba," but the other one did not say it. "And the 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.' News of this hadith reached Muawiyah and he stood up and said: 'What is the matter with men who narrate Hadiths from the Messenger of Allah when we accompanied him and we never heard him say it? News of that reached 'Ubadah bin As-Samit and he stood up and repeated the Hadith, then he said: 'We will narrate what we heard from the Messenger of Allah, whether Muawiyah likes it or not."' Qatadah contradicted him, he reported it from Muslim bin Yasar, from Abu Al-=Ashath, from 'Ubadah. (Using translation from Nasāʾī 4562)  

عُبَادَةُ نَهَى رَسُولُ اللهِ ﷺ عَنْ أَنْ نَبِيعَ الذَّهَبَ بِالذَّهَبِ وَالْوَرِقَ بِالْوَرِقِ وَالْبُرَّ بِالْبُرِّ وَالشَّعِيرَ بِالشَّعِيرِ وَالتَّمْرَ بِالتَّمْرِ فَقَالَ أَحَدُهُمَا وَالْمِلْحَ بِالْمِلْحِ وَلَمْ يَقُلِ الْآخَرُ إِلَّا سَوَاءً بِسَوَاءٍ مِثْلًا بِمِثْلٍ قَالَ أَحَدُهُمَا مَنْ زَادَ أَوِ ازْدَادَ فَقَدْ أَرْبَى وَلَمْ يَقُلْهُ الْآخَرُ وَأَمَرَنَا أَنْ نَبِيعَ الذَّهَبَ بِالْوَرِقِ وَالْوَرِقَ بِالذَّهَبِ وَالْبُرَّ بِالشَّعِيرِ وَالشَّعِيرَ بِالْبُرِّ يَدًا بِيَدٍ كَيْفَ شِئْنَا فَبَلَغَ الْحَدِيثُ مُعَاوِيَةَ فَقَامَ فَقَالَ مَا بَالُ رِجَالٍ يُحَدِّثُونَ أَحَادِيثَ عَنْ رَسُولِ اللهِ ﷺ قَدْ صَحِبْنَاهُ فَلَمْ نَسْمَعْهَا مِنْهُ فَبَلَغَ ذَلِكَ عُبَادَةَ فَقَامَ فَأَعَادَ الْحَدِيثَ وَقَالَ لَنُحَدِّثَنَّ بِمَا سَمِعْنَا مِنْ رَسُولِ اللهِ ﷺ وَإِنْ رُغِمَ مُعَاوِيَةُ خَالَفَهُ قَتَادَةُ فَرَوَاهُ عَنْ مُسْلِمِ بْنِ يَسَارٍ عَنْ أَبِي الْأَشْعَثِ عَنْ عُبَادَةَ  

"O people, you have invented kinds of transactions, I do not know what they are, but make sure it is gold for gold, of the same weight, or silver for silver, of the same weight. There is nothing wrong with selling silver for gold, hand to hand, giving more silver than gold, but no credit is allowed. When you sell wheat for wheat and barley for barley, it should be measure for measure, but there is nothing wrong with selling barley for wheat, hand to hand, giving more barley than wheat, but no credit is allowed. And when you sell dates for dates, it should be measure for measure" And he mentioned salt, "measure for measure, and whoever gives more or asks for more has engaged in Riba. (Using translation from Nasāʾī 4563)  

عَنْ عُبَادَةَ بْنِ الصَّامِتِ وَكَانَ بَدْرِيًّا وَكَانَ بَايَعَ رَسُولَ اللهِ ﷺ أَنْ لَا يَخَافَ فِي اللهِ لَوْمَةَ لَائِمٍ أَنَّ عُبَادَةَ بْنَ الصَّامِتِ قَامَ خَطِيبًا فَقَالَ أَيُّهَا النَّاسُ إِنَّكُمْ قَدْ أَحْدَثْتُمْ بُيُوعًا لَا أَدْرِي مَا هِيَ أَلَا إِنَّ الذَّهَبَ بِالذَّهَبِ وَزْنًا بِوَزْنٍ تِبْرُهَا وَعَيْنُهَا وَإِنَّ الْفِضَّةَ بِالْفِضَّةِ وَزْنًا بِوَزْنٍ تِبْرُهَا وَعَيْنُهَا وَلَا بَأْسَ بِبَيْعِ الْفِضَّةِ بِالذَّهَبِ يَدًا بَيْدٍ وَالْفِضَّةُ أَكْثَرُهُمَا وَلَا تَصْلُحُ نَسِيئَةً أَلَا إِنَّ الْبُرَّ بِالْبُرِّ وَالشَّعِيرَ بِالشَّعِيرِ مُدْيًا بِمُدْيٍ وَلَا بَأْسَ بِبَيْعِ الشَّعِيرِ بِالْحِنْطَةِ يَدًا بَيْدٍ وَالشَّعِيرُ أَكْثَرُهُمَا وَلَا يَصْلُحُ نَسِيئَةً أَلَا وَإِنَّ التَّمْرَ بِالتَّمْرِ مُدْيًا بِمُدْيٍ حَتَّى ذَكَرَ الْمِلْحَ مُدْيًا بِمُدْيٍ فَمَنْ زَادَ أَوِ اسْتَزَادَ فَقَدْ أَرْبَى  

"The messenger of Allah said: 'Gold for gold, of equal measure; silver for silver, of equal measure; salt for salt, dates for dates wheat for wheat, barley for barley, like for like. Whoever gives more or takes more has engaged in Riba."' (Sahih) The wording is that of Muhammad Yaqub did not mention - "Wheat for wheat". (Using translation from Nasāʾī 4564)   

قَالَ رَسُولُ اللهِ ﷺ «الذَّهَبُ بِالذَّهَبِ تِبْرُهُ وَعَيْنُهُ وَزْنًا بِوَزْنٍ وَالْفِضَّةُ بِالْفِضَّةِ تِبْرُهُ وَعَيْنُهُ وَزْنًا بِوَزْنٍ وَالْمِلْحُ بِالْمِلْحِ وَالتَّمْرُ بِالتَّمْرِ وَالْبُرُّ بِالْبُرِّ وَالشَّعِيرُ بِالشَّعِيرِ كَيْلًا بِكَيْلٍ فَمَنْ زَادَ أَوِ ازْدَادَ فَقَدْ أَرْبَى وَلَا بَأْسَ بِبَيْعِ الشَّعِيرِ بِالْبُرِّ وَالشَّعِيرُ أَكْثَرُهُمَا يَدًا بِيَدٍ»
