حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، سَمِعَ مَالِكَ بْنَ أَوْسِ بْنِ الْحَدَثَانِ، سَمِعَ عُمَرَ بْنَ الْخَطَّابِ، رَضِيَ اللَّهُ عَنْهُ يَقُولُ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَقَالَ سُفْيَانُ مَرَّةً سَمِعَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ الذَّهَبُ بِالْوَرِقِ رِبًا إِلَّا هَاءَ وَهَاءَ وَالْبُرُّ بِالْبُرِّ رِبًا إِلَّا هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلَّا هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلَّا هَاءَ وَهَاءَ.
