Gold is to be paid for by gold, silver by silver, wheat by wheat, barley by barley, dates by dates, and salt by salt, like for like and equal for equal, payment being made hand to hand. If these classes differ, then sell as you wish if payment is made hand to hand.  

قَالَ رَسُولُ اللَّهِ ﷺ الذَّهَبُ بِالذَّهَبِ وَالْفِضَّةُ بِالْفِضَّةِ وَالْبُرُّ بِالْبُرِّ وَالشَّعِيرُ بِالشَّعِيرِ وَالتَّمْرُ بِالتَّمْرِ وَالْمِلْحُ بِالْمِلْحِ مِثْلاً بِمِثْلٍ سَوَاءً بِسَوَاءٍ يَدًا بِيَدٍ فَإِذَا اخْتَلَفَتْ هَذِهِ الأَصْنَافُ فَبِيعُوا كَيْفَ شِئْتُمْ إِذَا كَانَ يَدًا بِيَدٍ  

Gold is to be paid for by gold, silver by silver, wheat by wheat, barley by barley, dates by dates, and salt by salt, like for like and equal for equal, payment being made hand to hand. If these classes differ, then sell as you wish if payment is made hand to hand. (Using translation from Muslim 1587c)  

قَالَ رَسُولُ اللهِ ﷺ الذَّهَبُ بِالذَّهَبِ وَالْفِضَّةُ بِالْفِضَّةِ وَالْبُرُّ بِالْبُرِّ وَالشَّعِيرُ بِالشَّعِيرِ وَالتَّمْرُ بِالتَّمْرِ وَالْمِلْحِ بِالْمِلْحِ مِثْلًا بِمِثْلٍ يَدًا بِيَدٍ فَإِذَا اخْتَلَفَتْ فِيهِ الْأَصْنَافُ فَبِيعُوا كَيْفَ شِئْتُمْ إِذَا كَانَ يَدًا بِيَدٍ  

[Machine] The Messenger of Allah ﷺ said, "Gold is to be exchanged for gold, silver for silver, wheat for wheat, barley for barley, dates for dates, and salt for salt, like for like, hand in hand. So, if these species differ, then sell as you wish if it is hand to hand."  

قَالَ رَسُولُ اللَّهِ ﷺ «الذَّهَبُ بِالذَّهَبِ وَالْفِضَّةُ بِالْفِضَّةِ وَالْبُرُّ بِالْبُرِّ وَالشَّعِيرُ بِالشَّعِيرِ مِثْلًا بِمِثْلٍ يَدًا بِيَدٍ فَإِذَا اخْتَلَفَتْ هَذِهِ الْأَصْنَافُ فَبِيعُوا كَيْفَ شِئْتُمْ إِذَا كَانَ يَدًا بِيَدٍ»  

[Machine] "He said that gold should be exchanged for gold, silver for silver, grain for grain, barley for barley, dates for dates, and salt for salt, like for like, equally, hand in hand. But if these commodities differ, then sell as you wish, as long as it is hand in hand. Abu Ali Al-Rudhbari informed us, I am Muhammad bin Bakr, Abu Dawood narrated to us, Abu Bakr bin Abi Shaybah narrated to us, I am Waqee', H and I am Abu Abdullah Al-Hafiz, I am Abu Al-Fadl bin Ibrahim, Ahmad bin Salamah narrated to us, Ishaq bin Ibrahim reported, and it was mentioned in the hadith."  

أَنَّهُ قَالَ الذَّهَبُ بِالذَّهَبِ وَالْفِضَّةُ بِالْفِضَّةِ وَالْبُرُّ بِالْبُرِّ وَالشَّعِيرُ بِالشَّعِيرِ وَالتَّمْرُ بِالتَّمْرِ وَالْمِلْحُ بِالْمِلْحِ مِثْلًا بِمِثْلٍ سَوَاءً بِسَوَاءٍ يَدًا بِيَدٍ فَإِذَا اخْتَلَفَ هَذِهِ الْأَصْنَافُ فَبِيعُوا كَيْفَ شِئْتُمْ إِذَا كَانَ يَدًا بِيَدٍ أَخْبَرَنَاهُ أَبُو عَلِيٍّ الرُّوذْبَارِيُّ أنا مُحَمَّدُ بْنُ بَكْرٍ ثنا أَبُو دَاوُدَ ثنا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ أنا وَكِيعٌ ح وَأنا أَبُو عَبْدِ اللهِ الْحَافِظُ أنا أَبُو الْفَضْلِ بْنُ إِبْرَاهِيمَ ثنا أَحْمَدُ بْنُ سَلَمَةَ ثنا إِسْحَاقُ بْنُ إِبْرَاهِيمَ أنبأ وَكِيعٌ ثنا سُفْيَانُ فَذَكَرَ الْحَدِيثَ  

Gold is to be paid for by gold, silver by silver, wheat by wheat, barley by barley, dates by dates, salt by salt, like by like, payment being made hand to hand. He who made an addition to it, or asked for an addition, in fact dealt in usury. The receiver and the giver are equally guilty. (Using translation from Muslim 1584e)   

قَالَ رَسُولُ اللهِ ﷺ الذَّهَبُ بِالذَّهَبِ وَالْفِضَّةُ بِالْفِضَّةِ وَالْبُرُّ بِالْبُرِّ وَالشَّعِيرُ بِالشَّعِيرِ وَالتَّمْرُ بِالتَّمْرِ وَالْمِلْحُ بِالْمِلْحِ مِثْلًا بِمِثْلِ يَدًا بِيَدٍ فَمَنْ زَادَ أَوِ ازْدَادَ فَقَدْ أَرْبَى الْآخِذُ وَالْمُعْطِي فِيهِ سَوَاءٌ  

"الذَّهبُ بالذَّهَبِ، والفضةُ بالفِضَّة، والبُرُّ بالبُرِّ، والشَّعِير بالشَّعِيرِ، والتَّمر بالتَّمْرِ، والمِلح بالمِلح، مِثْلًا بمثلٍ، سَواءً بسواءٍ، يدًا بيدٍ، فإِذا اخْتَلَفَتْ هذه الأَصنافُ، فَبِيعُوا كيفَ شِئْتُم إِذَا كانَ يدًا بيدٍ".
