"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
