[Machine] I heard Abu Usaid Al-Sa'idi and Ibn Abbas giving a fatwa (religious ruling) concerning the dinar. Abu Usaid strongly expressed his opinion, and Ibn Abbas said, "I did not expect anyone to know my close relationship to the Messenger of Allah ﷺ and say to me something like this, O Abu Usaid." Abu Usaid said, "I bear witness that I heard the Messenger of Allah ﷺ saying, 'The dinar should be exchanged with the dinar, the dirham with the dirham, the measure of wheat with the measure of wheat, the measure of barley with the measure of barley, and the measure of salt with the measure of salt. There should be no advantage in exchange of one for the other.'" Ibn Abbas said, "This is something I used to say based on my opinion, and I had not heard anything about it."
سَمِعْتُ أَبَا أُسَيْدٍ السَّاعِدِيَّ وَابْنُ عَبَّاسٍ يُفْتِي بِالدِّينَارِ بِالدِّينَارَيْنِ فَقَالَ أَبُو أُسَيْدٍ وَأَغْلَظَ لَهُ الْقَوْلَ فَقَالَ ابْنُ عَبَّاسٍ مَا كُنْتُ أَظُنُّ أَنَّ أَحَدًا يَعْرِفُ قَرَابَتِي مِنْ رَسُولِ اللهِ ﷺ يَقُولُ لِي مِثْلَ هَذَا يَا أَبَا أُسَيْدٍ فَقَالَ أَبُو أُسَيْدٍ أَشْهَدُ لَسَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «الدِّينَارُ بِالدِّينَارِ وَالدِّرْهَمُ بِالدِّرْهَمِ وَصَاعُ حِنْطَةٍ بِصَاعِ حِنْطَةٍ وَصَاعُ شَعِيرٍ بِصَاعِ شَعِيرٍ وَصَاعُ مِلْحٍ بِصَاعِ مِلْحٍ لَا فَضْلَ بَيْنَ شَيْءٍ مِنْ ذَلِكَ» فَقَالَ ابْنُ عَبَّاسٍ هَذَا شَيْءٌ كُنْتُ أَقُولُهُ بِرَأْيِي وَلَمْ أَسْمَعْ فِيهِ شَيْئًا
