I heard Abu Sa'id al-Khudri (Allah be pleased with him) said: Dinar (gold) for gold and dirham for dirham can be (exchanged) with equal for equal; but he who gives more or demands more in fact deals in interest. I sald to him: Ibn 'Abbas (Allah be pleased with them) says otherwise, whereupon he said: I met Ibn 'Abbas (Allah be pleased with them) and said: Do you see what you say; have you heard it from Messenger of Allah ﷺ, or found it in the Book of Allah, the Glorious and Majestic? He said: I did not hear it from Messenger of Allah ﷺ. and I did not find it in the Book of Allah (Glorious and Majestic), but Usama b. Zaid narrated it to me that Allah's Apostle ﷺ said: There can be an element of interest in credit.  

لَقَدْ لَقِيتُ ابْنَ عَبَّاسٍ فَقُلْتُ أَرَأَيْتَ هَذَا الَّذِي تَقُولُ أَشَىْءٌ سَمِعْتَهُ مِنْ رَسُولِ اللَّهِ ﷺ أَوْ وَجَدْتَهُ فِي كِتَابِ اللَّهِ ﷻ فَقَالَ لَمْ أَسْمَعْهُ مِنْ رَسُولِ اللَّهِ ﷺ وَلَمْ أَجِدْهُ فِي كِتَابِ اللَّهِ وَلَكِنْ حَدَّثَنِي أُسَامَةُ بْنُ زَيْدٍ أَنَّ النَّبِيَّ ﷺ قَالَ الرِّبَا فِي النَّسِيئَةِ  

"I said to Ibn Abbas: 'Do you think that what you are saying is something that you found in the Book of Allah, or something that you heard from the Messenger of Allah?' He said: 'I did not find it in the Book of Allah, nor did I hear it from the messenger of Allah, rather Usamah bin Zaid told me that the Messenger of Allah said: 'Riba is only in credit."'  

سَمِعَ أَبَا سَعِيدٍ الْخُدْرِيَّ يَقُولُ قُلْتُ لاِبْنِ عَبَّاسٍ أَرَأَيْتَ هَذَا الَّذِي تَقُولُ أَشَيْئًا وَجَدْتَهُ فِي كِتَابِ اللَّهِ ﷻ أَوْ شَيْئًا سَمِعْتَهُ مِنْ رَسُولِ اللَّهِ ﷺ قَالَ مَا وَجَدْتُهُ فِي كِتَابِ اللَّهِ ﷻ وَلاَ سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ﷺ وَلَكِنْ أُسَامَةُ بْنُ زَيْدٍ أَخْبَرَنِي أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّمَا الرِّبَا فِي النَّسِيئَةِ  

"I heard Abu Saeed Al-Khudri say: 'A Dirham for a Dirham and a Dinar for a Dinar.' So I said: 'I heard Ibn 'Abbas say something other than that.' He said: 'But I met Ibn 'Abbas and said: "Tell me about what you say concerning exchange is it something that you heard from the Messenger of Allah ﷺ or something that You found in the Book of Allah?" He said: "I did not find it in the Book of Allah, and I did not hear it from the Messenger of Allah; rather Usamah bin Zaid told me that the Messenger of Allah ﷺ said: "Usury is only in credit."[1]  

سَمِعْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ يَقُولُ الدِّرْهَمُ بِالدِّرْهَمِ وَالدِّينَارُ بِالدِّينَارِ فَقُلْتُ إِنِّي سَمِعْتُ ابْنَ عَبَّاسٍ يَقُولُ غَيْرَ ذَلِكَ قَالَ أَمَا إِنِّي لَقِيتُ ابْنَ عَبَّاسٍ فَقُلْتُ أَخْبِرْنِي عَنْ هَذَا الَّذِي تَقُولُ فِي الصَّرْفِ أَشَىْءٌ سَمِعْتَهُ مِنْ رَسُولِ اللَّهِ ﷺ أَمْ شَىْءٌ وَجَدْتَهُ فِي كِتَابِ اللَّهِ فَقَالَ مَا وَجَدْتُهُ فِي كِتَابِ اللَّهِ وَلاَ سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ وَلَكِنْ أَخْبَرَنِي أُسَامَةُ بْنُ زَيْدٍ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّمَا الرِّبَا فِي النَّسِيئَةِ

He said: 'I did not find it in the Book of Allah, nor did I hear it from the messenger of Allah, rather Usamah bin Zaid told me that the Messenger of Allah said: 'Riba is only in credit."' (Using translation from Nasāʾī 4581)  

سَمِعَ أَبَا سَعِيدٍ الْخُدْرِيَّ يَقُولُ قُلْتُ لِابْنِ عَبَّاسٍ أَرَأَيْتَ هَذَا الَّذِي تَقُولُ أَشَيْئًا وَجَدْتَهُ فِي كِتَابِ اللهِ أَوْ سَمِعْتَهُ مِنْ رَسُولِ اللهِ ﷺ؟ قَالَ مَا وَجَدْتُهُ فِي كِتَابِ اللهِ وَلَا سَمِعْتُهُ مِنْ رَسُولِ اللهِ ﷺ وَلَكِنْ أُسَامَةُ بْنُ زَيْدٍ أَخْبَرَنِي أَنَّ رَسُولَ اللهِ ﷺ قَالَ «إِنَّمَا الرِّبَا فِي النَّسِيئَةِ»
