[Machine] The Messenger of Allah ﷺ said on one day while he was with his wife Umm Salamah: "I desire some date palm (type of dates) called 'ajwah'. So she sent two handfuls of dates to a man from the Ansar (helpers of the Prophet). He brought back two handfuls of 'ajwah dates instead. She presented them to the Messenger of Allah ﷺ , and when he saw them, he was pleased. He took one date, then another, and then he held them and said, 'Where did you get these?' Umm Salamah said, 'I sent two handfuls of dates to a man from the Ansar, and he brought back two handfuls of these 'ajwah dates.' This is one of the handfuls.' He held the dates out before him and said, 'Return it; I have no need for this. Dates should be exchanged for dates, barley for barley, wheat for wheat, gold for gold, silver for silver, hand to hand, like for like, equal for equal. If there is more, it is usury.' Then he said, 'This is how it should be weighed and measured.' Ibn Abbas said, 'May Allah reward you, O Abu Sa'id, with Paradise, for you reminded me of something I had forgotten. I seek forgiveness from Allah and repent to Him.' After that, he disliked it (usury), and prohibited it more strongly."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ ذَاتَ يَوْمٍ وَهُوَ عِنْدَ زَوْجَتِهِ أُمِّ سَلَمَةَ إِنِّي لَأَشْتَهِي تَمْرَ عَجْوَةٍ فَبَعَثَتْ صَاعَيْنِ مِنْ تَمْرٍ إِلَى رَجُلٍ مِنَ الْأَنْصَارِ فَجَاءَ بَدَلَ صَاعَيْنِ صَاعٌ مِنْ تَمْرٍ عَجْوَةٍ فَقَامَتْ فَقَدَّمَتْهُ إِلَى رَسُولِ اللَّهِ ﷺ فَلَمَّا رَآهُ أَعْجَبَهُ فَتَنَاوَلَ تَمْرَةً ثُمَّ أَمْسَكَ فَقَالَ «مِنْ أَيْنَ لَكُمْ هَذَا؟» فَقَالَتْ أُمُّ سَلَمَةَ بَعَثْتُ صَاعَيْنِ مِنْ تَمْرٍ إِلَى رَجُلٍ مِنَ الْأَنْصَارِ فَأَتَانَا بَدَلَ صَاعَيْنِ هَذَا الصَّاعُ الْوَاحِدُ وَهَا هُوَ كُلْ فَأَلْقَى التَّمْرَةَ بَيْنَ يَدَيْهِ فَقَالَ «رُدُّوهُ لَا حَاجَةَ لِي فِيهِ التَّمْرُ بِالتَّمْرِ وَالْحِنْطَةُ بِالْحِنْطَةِ وَالشَّعِيرُ بِالشَّعِيرِ وَالذَّهَبُ بِالذَّهَبِ وَالْفِضَّةُ بِالْفِضَّةِ يَدًا بِيَدٍ عَيْنًا بِعَيْنٍ مِثْلًا بِمِثْلٍ فَمَنْ زَادَ فَهُوَ رِبًا» ثُمَّ قَالَ «كَذَلِكَ مَا يُكَالُ وَيُوزَنُ أَيْضًا» فَقَالَ ابْنُ عَبَّاسٍ جَزَاكَ اللَّهُ يَا أَبَا سَعِيدٍ الْجَنَّةَ فَإِنَّكَ ذَكَّرْتَنِي أَمْرًا كُنْتُ نَسِيتُهُ أَسْتَغْفِرُ اللَّهَ وَأَتُوبُ إِلَيْهِ فَكَانَ يَنْهَى عَنْهُ بَعْدَ ذَلِكَ أَشَدَّ النَّهْيِ
