It was narrated that abu Al-Minhal said:

"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 (ﷺ) 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."

أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، عَنْ سُفْيَانَ، عَنْ عَمْرٍو، عَنْ أَبِي الْمِنْهَالِ، قَالَ 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 صلى الله عليه وسلم 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 ‏.‏
