عَنْ يَحْيَى بْنِ قَيْسٍ الْمَازَنِيِّ قَالَ سَأَلْتُ عَطَاءً عَنِ الدِّينَارِ بِالدِّينَارِ وَبَيْنَهُمَا فَضْلٌ وَالدِّرْهَمِ بِالدِّرْهَمِ قَالَ كَانَ ابْنُ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا يُحِلُّهُ فَقَالَ ابْنُ الزُّبَيْرِ إِنَّ ابْنَ عَبَّاسٍ يُحَدِّثُ بِمَا لَمْ يَسْمَعْ مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَبَلَغَ ابْنَ عَبَّاسٍ فَقَالَ إِنِّي لَمْ أَسْمَعْهُ مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَلَكِنْ أُسَامَةُ بْنُ زَيْدٍ رَضِيَ اللَّهُ عَنْهُ حَدَّثَنِي أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ لَيْسَ الرِّبَا إِلَّا فِي النَّسِيئَةِ أَوِ النَّظِرَةِ
Yahya bin Qais Mazni says: I asked Imam Ata whether, when trading dinar for dinar and dirham for dirham, there can be any increase or decrease. He said: Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) considered it permissible. Sayyiduna Ibn Zubair (may Allah be pleased with them both) said: Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates matters which he did not himself hear from the Messenger of Allah (peace and blessings be upon him). When this reached him, he said: Indeed, I did not myself hear this hadith from the Messenger of Allah (peace and blessings be upon him), but Sayyiduna Usama bin Zaid (may Allah be pleased with them both) narrated to me that the Messenger of Allah (peace and blessings be upon him) said that there is no usury except in credit.
