عَنْ أَبِي الْمِنْهَالِ قَالَ سَأَلْتُ الْبَرَاءَ بْنَ عَازِبٍ وَزَيْدَ بْنَ أَرْقَمَ رَضِيَ اللَّهُ عَنْهُمَا عَنِ الصَّرْفِ فَهَذَا يَقُولُ سَلْ هَذَا فَإِنَّهُ خَيْرٌ مِنِّي وَأَعْلَمُ وَهَذَا يَقُولُ سَلْ هَذَا فَهُوَ خَيْرٌ مِنِّي وَأَعْلَمُ قَالَ فَسَأَلْتُهُمَا فَكِلَاهُمَا يَقُولُ نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَنْ بَيْعِ الْوَرِقِ بِالذَّهَبِ دَيْنًا
Abu Minhal says: I asked Sayyiduna Bara’ bin Azib and Sayyiduna Zayd bin Arqam (may Allah be pleased with them both) about the exchange of gold and silver, but one of them said: Ask him, for he is better and more knowledgeable than me, and the other said: Ask him, for he is better and more knowledgeable than me. Then I asked both of them, and both said: The Messenger of Allah (peace and blessings be upon him) forbade selling gold for silver on credit.
