Sahih Muslim 1589a
Abu Minhal reported: My partner sold silver to be paid in the (Hajj) season or (in the days of) Hajj. He (my partner) came to me and informed me, and I said to him: Such transaction is not desirable. He said: I sold it in the market (on loan) but nobody objected to this. I went to al-Bara' b. 'Azib and asked him, and he said: Allah's Apostle ﷺ came to Medina and we made such transaction, whereupon he said: In case the payment is made on the spot, there is no harm in it, and in case (it is 'sold) on loan, it is usury. You better go to Zaid b. Arqam, for he is a greater trader than I;
so I went to him and asked him, and he said like it.
حَدَّثَنَا مُحَمَّدُ بْنُ حَاتِمِ بْنِ مَيْمُونٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عَمْرٍو، عَنْ أَبِي، الْمِنْهَالِ قَالَ بَاعَ شَرِيكٌ لِي وَرِقًا بِنَسِيئَةٍ إِلَى الْمَوْسِمِ أَوْ إِلَى الْحَجِّ فَجَاءَ إِلَىَّ فَأَخْبَرَنِي فَقُلْتُ هَذَا أَمْرٌ لاَ يَصْلُحُ . قَالَ قَدْ بِعْتُهُ فِي السُّوقِ فَلَمْ يُنْكِرْ ذَلِكَ عَلَىَّ أَحَدٌ . فَأَتَيْتُ الْبَرَاءَ بْنَ عَازِبٍ فَسَأَلْتُهُ فَقَالَ قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ وَنَحْنُ نَبِيعُ هَذَا الْبَيْعَ فَقَالَ " مَا كَانَ يَدًا بِيَدٍ فَلاَ بَأْسَ بِهِ وَمَا كَانَ نَسِيئَةً فَهُوَ رِبًا " . وَائْتِ زَيْدَ بْنَ أَرْقَمَ فَإِنَّهُ أَعْظَمُ تِجَارَةً مِنِّي . فَأَتَيْتُهُ فَسَأَلْتُهُ فَقَالَ مِثْلَ ذَلِكَ .
