Sahih Muslim Book - 22, Hadith - 4091

حَدَّثَنَا الْحَكَمُ بْنُ مُوسَى حَدَّثَنَا هِقْلٌ عَنِ الأَوْزَاعِىِّ قَالَ حَدَّثَنِى عَطَاءُ بْنُ أَبِى رَبَاحٍ أَنَّ أَبَا سَعِيدٍ الْخُدْرِىَّ لَقِىَ ابْنَ عَبَّاسٍ فَقَالَ لَهُ أَرَأَيْتَ قَوْلَكَ فِى الصَّرْفِ أَشَيْئًا سَمِعْتَهُ مِنْ رَسُولِ اللَّهِ -صلى الله عليه وسلم- أَمْ شَيْئًا وَجَدْتَهُ فِى كِتَابِ اللَّهِ عَزَّ وَجَلَّ فَقَالَ ابْنُ عَبَّاسٍ كَلاَّ لاَ أَقُولُ أَمَّا رَسُولُ اللَّهِ -صلى الله عليه وسلم- فَأَنْتُمْ أَعْلَمُ بِهِ وَأَمَّا كِتَابُ اللَّهِ فَلاَ أَعْلَمُهُ وَلَكِنْ حَدَّثَنِى أُسَامَةُ بْنُ زَيْدٍ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- قَالَ « أَلاَ إِنَّمَا الرِّبَا فِى النَّسِيئَةِ ».

'Ata' bin Abi Rahah narrated that Abu Sa'eed Al-Khudri met Ibn 'Abbas and said to him: "Do you think that what you said about exchange is something that you heard from the Messenger of Allah (s.a.w) or something that" you found in the Book of Allah?" Ibn 'Abbas said: "I do not say that it is either of them. As for the Messenger of Allah (s.a.w), you are more knowledgeable than me, and as for the Book of Allah, I do not know it better (than you), but Usamah bin Zaid told me that the Messenger of Allah (s.a.w) said: 'Indeed, Riba is only in the case of delayed payment."'
