"The Messenger of Allah forbade selling silver for silver and gold for gold, unless it was of equal amounts. And he told us to sell gold for silver however we wanted, and silver for gold however we wanted.  

نَهَى رَسُولُ اللَّهِ ﷺ عَنْ بَيْعِ الْفِضَّةِ بِالْفِضَّةِ وَالذَّهَبِ بِالذَّهَبِ إِلاَّ سَوَاءً بِسَوَاءٍ وَأَمَرَنَا أَنْ نَبْتَاعَ الذَّهَبَ بِالْفِضَّةِ كَيْفَ شِئْنَا وَالْفِضَّةَ بِالذَّهَبِ كَيْفَ شِئْنَا  

"The Messenger of Allah forbade us from selling silver for silver unless it was of equal amounts, or selling gold for gold unless it was of equal amounts. The messenger of Allah said: 'Sell gold for silver however you want, and silver for gold however you want."'  

نَهَانَا رَسُولُ اللَّهِ ﷺ أَنْ نَبِيعَ الْفِضَّةَ بِالْفِضَّةِ إِلاَّ عَيْنًا بِعَيْنٍ سَوَاءً بِسَوَاءٍ وَلاَ نَبِيعَ الذَّهَبَ بِالذَّهَبِ إِلاَّ عَيْنًا بِعَيْنٍ سَوَاءً بِسَوَاءٍ قَالَ رَسُولُ اللَّهِ ﷺ تَبَايَعُوا الذَّهَبَ بِالْفِضَّةِ كَيْفَ شِئْتُمْ وَالْفِضَّةَ بِالذَّهَبِ كَيْفَ شِئْتُمْ  

"There is no Riba except in credit.'  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ رِبًا إِلاَّ 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 used to sell camels at Al-Baqi and I would sell Dinars in exchange for Dirhams. I came to the Prophet in the house of Hafsah and said: 'O Messenger of Allah, I want to ask you: I sell camels in Al-Baqi and I sell Dinars in exchange for Dirhams. He said: 'There is nothing wrong with it if you take the price on that day, unless you depart when there is still unfinished business between you both (buyer and seller)."'  

كُنْتُ أَبِيعُ الإِبِلَ بِالْبَقِيعِ فَأَبِيعُ بِالدَّنَانِيرِ وَآخُذُ الدَّرَاهِمَ فَأَتَيْتُ النَّبِيَّ ﷺ فِي بَيْتِ حَفْصَةَ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنِّي أُرِيدُ أَنْ أَسْأَلَكَ إِنِّي أَبِيعُ الإِبِلَ بِالْبَقِيعِ فَأَبِيعُ بِالدَّنَانِيرِ وَآخُذُ الدَّرَاهِمَ قَالَ لاَ بَأْسَ أَنْ تَأْخُذَهَا بِسِعْرِ يَوْمِهَا مَا لَمْ تَفْتَرِقَا وَبَيْنَكُمَا شَىْءٌ
