Sahih Muslim , Hadith 1590 ⓘ
Abd al-Rabman b. Abia Bakra reported on the authority of his father that Allah's Messenger forbade the sale of gold for gold, and silver for silver except equal for equal, and commanded us to buy silver for gold as we desired and buy gold for silver as we desired. A person asked him (about the nature of payment), whereupon he said: It is to be made on the spot. This is what I heard (from Allah's Messenger (may peace be upon him ).
حَدَّثَنَا أَبُو الرَّبِيعِ الْعَتَكِيُّ، حَدَّثَنَا عَبَّادُ بْنُ الْعَوَّامِ، أَخْبَرَنَا يَحْيَى بْنُ أَبِي إِسْحَاقَ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ أَبِي بَكْرَةَ، عَنْ أَبِيهِ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ الْفِضَّةِ بِالْفِضَّةِ وَالذَّهَبِ بِالذَّهَبِ إِلاَّ سَوَاءً بِسَوَاءٍ وَأَمَرَنَا أَنْ نَشْتَرِيَ الْفِضَّةَ بِالذَّهَبِ كَيْفَ شِئْنَا وَنَشْتَرِيَ الذَّهَبَ بِالْفِضَّةِ كَيْفَ شِئْنَا . قَالَ فَسَأَلَهُ رَجُلٌ فَقَالَ يَدًا بِيَدٍ فَقَالَ هَكَذَا سَمِعْتُ .

Abd al-Rabman b. Abu Bakra said: Allah's Messenger prohibited us. The rest of the hadith is the same.
حَدَّثَنِي إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا يَحْيَى بْنُ صَالِحٍ، حَدَّثَنَا مُعَاوِيَةُ، عَنْ يَحْيَى، - وَهُوَ ابْنُ أَبِي كَثِيرٍ - عَنْ يَحْيَى بْنِ أَبِي إِسْحَاقَ، أَنَّ عَبْدَ الرَّحْمَنِ بْنَ أَبِي بَكْرَةَ، أَخْبَرَهُ أَنَّ أَبَا بَكْرَةَ قَالَ نَهَانَا رَسُولُ اللَّهِ صلى الله عليه وسلم بِمِثْلِهِ .
