[Machine] I heard Umar ibn al-Khattab say that the Messenger of Allah ﷺ used to say on the pulpit, "Gold for gold is usury unless equal for equal with no increase. Whatever exceeds that is usury." Ibn Umar said, "If you are in doubt, then ask Abu Sa'eed al-Khudri about it." So he went and asked Abu Sa'eed al-Khudri, who confirmed that he heard it from the Messenger of Allah ﷺ . Ibn Abbas was asked about what Ibn Umar and Abu Sa'eed said, and he sought forgiveness and said, "This is an opinion that I have seen."  

سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ يَقُولُ كَانَ رَسُولُ اللهِ ﷺ يَقُولُ عَلَى الْمِنْبَرِ «الذَّهَبُ بِالذَّهَبِ رِبًا إِلَّا مِثْلًا بِمِثْلِ لَا زِيَادَةَ فَمَا زَادَ فَهُوَ رِبًا» قَالَ ابْنُ عُمَرَ فَإِنْ كُنْتَ فِي شَكٍّ فَاسْأَلْ أَبَا سَعِيدٍ الْخُدْرِيَّ عَنْ ذَلِكَ فَانْطَلَقَ فَسَأَلَ أَبَا سَعِيدٍ الْخُدْرِيَّ فَأَخْبَرَهُ أَنَّهُ سَمِعَ ذَلِكَ مِنْ رَسُولِ اللهِ ﷺ فَقِيلَ لِابْنِ عَبَّاسٍ مَا قَالَ ابْنُ عُمَرَ وَأَبُو سَعِيدٍ فَاسْتَغْفَرَ ابْنُ عَبَّاسٍ وَقَالَ هَذَا رَأْيٌ رَأَيْتُهُ
