muslim:1589b – ʿUbaydullāh b. Muʿādh al-ʿAnbarī from my father > Shuʿbah > Ḥabīb > Abū al-Minhāl > Saʾalt al-Barāʾ b. ʿĀzib > al-Ṣarf > Sal Zayd b. Arqam Fahū Aʿlam Fasaʾalt Zayd > Sal al-Barāʾ Faʾinnah Aʿlam Thum

I asked al-Bara' b. Azib about the exchange of (gold for silver or vice versa), whereupon he said: you better ask Zaid b. Arqam for he knows more than I. So I asked Zaid but he said: You better ask al-Bara' for he knows more than I. Then both of them said: Messenger of Allah ﷺ forbade the sale of silver for gold when payment is to be made in future.  

مسلم:١٥٨٩b – حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ حَدَّثَنَا أَبِي حَدَّثَنَا شُعْبَةُ عَنْ حَبِيبٍ أَنَّهُ سَمِعَ أَبَا الْمِنْهَالِ يَقُولُ سَأَلْتُ الْبَرَاءَ بْنَ عَازِبٍ عَنِ الصَّرْفِ فَقَالَ سَلْ زَيْدَ بْنَ أَرْقَمَ فَهُوَ أَعْلَمُ فَسَأَلْتُ زَيْدًا فَقَالَ

سَلِ الْبَرَاءَ فَإِنَّهُ أَعْلَمُ ثُمَّ قَالاَ نَهَى رَسُولُ اللَّهِ ﷺ عَنْ بَيْعِ الْوَرِقِ بِالذَّهَبِ دَيْنًا
