[Machine] I heard the Messenger of Allah ﷺ say, "Gold is exchanged for gold, silver for silver, dates for dates, wheat for wheat, and barley for barley. There should be equal amounts and no excess."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «الذَّهَبُ بِالذَّهَبِ هَاءَ وَهَاءَ وَالْفِضَّةُ بِالْفِضَّةِ هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ هَاءَ وَهَاءَ وَالْبُرُّ بِالْبُرِّ هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ هَاءَ وَهَاءَ وَلَا فَضْلَ بَيْنَهُمَا»  

[Machine] The Prophet ﷺ prohibited selling gold for gold, silver for silver, wheat for wheat, dates for dates, barley for barley, and salt for salt, except in equal amounts and at the same time. Whoever adds more or asks for more has practiced usury.  

إِنَّ رَسُولَ اللَّهِ ﷺ «نَهَى عَنْ بَيْعِ الذَّهَبِ بِالذَّهَبِ وَالْفِضَّةِ بِالْفِضَّةِ وَالْبُرِّ بِالْبُرِّ وَالتَّمْرِ بِالتَّمْرِ وَالشَّعِيرِ بِالشَّعِيرِ وَالْمِلْحِ بِالْمِلْحِ إِلَّا مِثْلًا بِمِثْلٍ سَوَاءً بِسَوَاءٍ فَمَنْ زَادَ أَوِ ازْدَادَ فَقَدْ أَرْبَى»
