Bilal (Allah be pleased with him) came with fine quality of dates. Messenger of Allah ﷺ said to him: From where (you have brought them)? Bilal said: We had inferior quality of dates and I exchanged two sa's (of inferior quality) with one sa (of fine quality) as food for Allah's Apostle ﷺ, whereupon Messenger of Allah ﷺ said: Woe! it is in fact usury; therefore, don't do that. But when you intend to buy dates (of superior quality), sell (the inferior quality) in a separate bargain and then buy (the superior quality). And in the hadith transmitted by Ibn Sahl there is no mention of" whereupon".  

مسلم:١٥٩٤a – حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ أَخْبَرَنَا يَحْيَى بْنُ صَالِحٍ الْوُحَاظِيُّ حَدَّثَنَا مُعَاوِيَةُ ح وَحَدَّثَنِي مُحَمَّدُ بْنُ سَهْلٍ التَّمِيمِيُّ وَعَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ الدَّارِمِيُّ وَاللَّفْظُ لَهُمَا جَمِيعًا عَنْ يَحْيَى بْنِ حَسَّانَ حَدَّثَنَا مُعَاوِيَةُ وَهُوَ ابْنُ سَلاَّمٍ أَخْبَرَنِي يَحْيَى وَهُوَ ابْنُ أَبِي كَثِيرٍ قَالَ سَمِعْتُ عُقْبَةَ بْنَ عَبْدِ الْغَافِرِ يَقُولُ

سَمِعْتُ أَبَا سَعِيدٍ يَقُولُ جَاءَ بِلاَلٌ بِتَمْرٍ بَرْنِيٍّ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ مِنْ أَيْنَ هَذَا فَقَالَ بِلاَلٌ تَمْرٌ كَانَ عِنْدَنَا رَدِيءٌ فَبِعْتُ مِنْهُ صَاعَيْنِ بِصَاعٍ لِمَطْعَمِ النَّبِيِّ ﷺ فَقَالَ رَسُولُ اللَّهِ عِنْدَ ذَلِكَ أَوَّهْ عَيْنُ الرِّبَا لاَ تَفْعَلْ وَلَكِنْ إِذَا أَرَدْتَ أَنْ تَشْتَرِيَ التَّمْرَ فَبِعْهُ بِبَيْعٍ آخَرَ ثُمَّ اشْتَرِ بِهِ لَمْ يَذْكُرِ ابْنُ سَهْلٍ فِي حَدِيثِهِ عِنْدَ ذَلِكَ

Once Bilal brought Barni (i.e. a kind of dates) to the Prophet ﷺ and the Prophet ﷺ asked him, "From where have you brought these?" Bilal replied, "I had some inferior type of dates and exchanged two Sas of it for one Sa of Barni dates in order to give it to the Prophet; to eat." Thereupon the Prophet ﷺ said, "Beware! Beware! This is definitely Riba (usury)! This is definitely Riba (Usury)! Don't do so, but if you want to buy (a superior kind of dates) sell the inferior dates for money and then buy the superior kind of dates with that money."

أَنَّهُ سَمِعَ أَبَا سَعِيدٍ الْخُدْرِيَّ ؓ قَالَ جَاءَ بِلاَلٌ إِلَى النَّبِيِّ ﷺ بِتَمْرٍ بَرْنِيٍّ فَقَالَ لَهُ النَّبِيُّ ﷺ مِنْ أَيْنَ هَذَا قَالَ بِلاَلٌ كَانَ عِنْدَنَا تَمْرٌ رَدِيٌّ فَبِعْتُ مِنْهُ صَاعَيْنِ بِصَاعٍ لِنُطْعِمَ النَّبِيَّ ﷺ فَقَالَ النَّبِيُّ ﷺ عِنْدَ ذَلِكَ أَوَّهْ أَوَّهْ عَيْنُ الرِّبَا عَيْنُ الرِّبَا لاَ تَفْعَلْ وَلَكِنْ إِذَا أَرَدْتَ أَنْ تَشْتَرِيَ فَبِعِ التَّمْرَ بِبَيْعٍ آخَرَ ثُمَّ اشْتَرِهِ
