و حَدَّثَنَا سَلَمَةُ بْنُ شَبِيبٍ حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ حَدَّثَنَا مَعْقِلٌ عَنْ أَبِي قَزَعَةَ الْبَاهِلِيِّ عَنْ أَبِي نَضْرَةَ عَنْ أَبِي سَعِيدٍ قَالَ أُتِيَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ بِتَمْرٍ فَقَالَ مَا هَذَا التَّمْرُ مِنْ تَمْرِنَا فَقَالَ الرَّجُلُ يَا رَسُولَ اللَّهِ بِعْنَا تَمْرَنَا صَاعَيْنِ بِصَاعٍ مِنْ هَذَا فَقَالَ رَسُولُ اللَّهِ هَذَا الرِّبَا فَرُدُّوهُ ثُمَّ بِيعُوا تَمْرَنَا وَاشْتَرُوا لَنَا مِنْ هَذَا
صحیح مسلم · Hadith 4084
Abd Sa'id reported: Bilal (Allah be pleased with him) came with fine quality of dates. Allah's Messenger ( صلی اللہ علیہ وسلم ) 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 ( صلی اللہ علیہ وسلم ), whereupon Allah's Messenger ( صلی اللہ علیہ وسلم ) 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 .
