"Sharik sold some silver on credit for me. He came to me and told me. And I said: 'This is not correct.' He said; 'By Allah, I did this transaction in the market and no one criticized me .' So I went to Al-Bara bin Azib and asked him about that. He said: 'The Prophet came to us in Al-Madinah and we used to do this kind of transaction, but he said: Whatever is hand to hand, there is nothing wrong with it, but whatever is on credit, is Riba. Then he said to me: 'Go to Zaid bin Arqam.' So I went to him and asked him, and he said the same thing."  

بَاعَ شَرِيكٌ لِي وَرِقًا بِنَسِيئَةٍ فَجَاءَنِي فَأَخْبَرَنِي فَقُلْتُ هَذَا لاَ يَصْلُحُ فَقَالَ قَدْ وَاللَّهِ بِعْتُهُ فِي السُّوقِ وَمَا عَابَهُ عَلَىَّ أَحَدٌ فَأَتَيْتُ الْبَرَاءَ بْنَ عَازِبٍ فَسَأَلْتُهُ فَقَالَ قَدِمَ عَلَيْنَا النَّبِيُّ ﷺ الْمَدِينَةَ وَنَحْنُ نَبِيعُ هَذَا الْبَيْعَ فَقَالَ مَا كَانَ يَدًا بِيَدٍ فَلاَ بَأْسَ وَمَا كَانَ نَسِيئَةً فَهُوَ رِبًا ثُمَّ قَالَ لِي ائْتِ زَيْدَ بْنَ أَرْقَمَ فَأَتَيْتُهُ فَسَأَلْتُهُ فَقَالَ مِثْلَ ذَلِكَ  

" I asked Al-Bara bin 'Azib and Zaid bin Arqam and they said: 'We were merchants at the time of the Messenger of Allah and we asked the Prophet of Allah about money exchange. He said: "If it is done hand to hand there is nothing wrong with it, but if it is done on credit then it is not right."  

أَخْبَرَنِي عَمْرُو بْنُ دِينَارٍ وَعَامِرُ بْنُ مُصْعَبٍ أَنَّهُمَا سَمِعَا أَبَا الْمِنْهَالِ يَقُولُ سَأَلْتُ الْبَرَاءَ بْنَ عَازِبٍ وَزَيْدَ بْنَ أَرْقَمَ فَقَالاَ كُنَّا تَاجِرَيْنِ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فَسَأَلْنَا نَبِيَّ اللَّهِ ﷺ عَنِ الصَّرْفِ فَقَالَ إِنْ كَانَ يَدًا بِيَدٍ فَلاَ بَأْسَ وَإِنْ كَانَ نَسِيئَةً فَلاَ يَصْلُحُ  

"I asked Al-Bara bin 'Azib about money exchange. He said: 'Ask Zaid bin Arqam, for he is better than me and more knowledgeable.' So I asked Zaid and he said: 'Ask Al-Bara for he is better than me and more knowledgeable.' And they both said: 'The Messenger of Allah forbade (selling) silver for gold on credit."'  

سَلِ الْبَرَاءَ فَإِنَّهُ خَيْرٌ مِنِّي وَأَعْلَمُ فَقَالاَ جَمِيعًا نَهَى رَسُولُ اللَّهِ ﷺ عَنِ الْوَرِقِ بِالذَّهَبِ دَيْنًا
