[Machine] I heard Abu Al-Minhal say that he asked Al-Bara' bin 'Azib about Sarf (a linguistic term). Al-Bara' replied, "Ask Zaid bin Arqam as he is better and more knowledgeable than me." He then asked Zaid, who said, "Ask Al-Bara' as he is better and more knowledgeable than me." Finally, they both said, "The Messenger of Allah ﷺ forbade selling paper for gold as a debt."
سَمِعْتُ أَبَا الْمِنْهَالِ رَجُلًا مِنْ بَنِي كِنَانَةَ قَالَ سَأَلْتُ الْبَرَاءَ بْنَ عَازِبٍ عَنِ الصَّرْفِ؟ فَقَالَ سَلْ زَيْدَ بْنَ أَرْقَمَ فَإِنَّهُ خَيْرٌ مِنِّي وَأَعْلَمُ قَالَ فَسَأَلْتُ زَيْدًا فَقَالَ سَلِ الْبَرَاءَ فَإِنَّهُ خَيْرٌ مِنِّي وَأَعْلَمُ قَالَ فَقَالَا جَمِيعًا نَهَى رَسُولُ اللهِ ﷺ عَنْ بَيْعِ الْوَرِقِ بِالذَّهَبِ دَيْنًا
