[Machine] O people, you have introduced transactions, I don't know what they are. And indeed, gold with gold should be hand to hand in equal amounts, and silver with silver should be hand to hand in equal amounts. Women should not be exchanged for women, and barley should be exchanged for barley, measure for measure, hand to hand. It is permissible to exchange barley for wheat and the majority of them can be hand to hand. Women should not be exchanged for bad ones. Dates with dates should be exchanged until the salt is counted with salt, like for like, hand to hand. Whoever adds or increases, then he has committed riba. Qatadah said, "Ubadah bin Samit, one of the leaders of the Ansar, gave allegiance to the Messenger of Allah ﷺ that he would not fear the blame of any blamer."
يَا أَيُّهَا النَّاسُ إِنَّكُمْ قَدْ أَحْدَثْتُمْ بُيُوعًا مَا أَدْرِي مَا هِيَ؟ وَإِنَّ الذَّهَبَ بِالذَّهَبِ تِبْرُهُ وَعَيْنُهُ وَزْنًا بِوَزْنٍ يَدًا بِيَدٍ وَالْفِضَّةُ بِالْفِضَّةِ وَزْنًا بِوَزْنٍ يَدًا بِيَدٍ وَلَا يَصْلُحُ نَسَاءً وَالْبُرُّ بِالْبُرِّ مُدًّا بِمُدٍّ يَدًا بِيَدٍ وَالشَّعِيرُ بِالشَّعِيرِ مُدًّا بِمُدٍّ يَدًا بِيَدٍ وَلَا بَأْسَ بِبَيْعِ الشَّعِيرِ بِالْبُرِّ وَالشَّعِيرُ أَكْثَرُهُمَا يَدًا بِيَدٍ وَلَا يَصْلُحُ نَسِيئَةً وَالتَّمْرُ بِالتَّمْرِ حَتَّى عَدَّ الْمِلْحَ بِالْمِلْحِ مِثْلًا بِمِثْلٍ يَدًا بِيَدٍ مَنْ زَادَ أَوِ ازْدَادَ فَقَدْ أَرْبَى قَالَ قَتَادَةُ وَكَانَ عُبَادَةُ بَدْرِيًّا عَقَبِيًّا أَحَدَ نُقَبَاءِ الْأَنْصَارِ وَكَانَ بَايَعَ رَسُولَ اللهِ ﷺ عَلَى أَنْ لَا يَخَافَ فِي اللهِ لَوْمَةَ لَائِمٍ كَذَا
