Sunan at-Tirmithiy كتاب البيوع باب ما جاء فى الصرف
حَدَّثَنَا قُتَيْبَةُ حَدَّثَنَا اللَّيْثُ عَنِ ابْنِ شِهَابٍ عَنْ مَالِكِ بْنِ أَوْسِ بْنِ الْحَدَثَانِ أَنَّهُ قَالَ أَقْبَلْتُ أَقُولُ مَنْ يَصْطَرِفُ الدَّرَاهِمَ فَقَالَ طَلْحَةُ بْنُ عُبَيْدِ اللَّهِ وَهُوَ عِنْدَ عُمَرَ بْنِ الْخَطَّابِ أَرِنَا ذَهَبَكَ ثُمَّ ائْتِنَا إِذَا جَاءَ خَادِمُنَا نُعْطِكَ وَرِقَكَ. فَقَالَ عُمَرُ كَلاَّ وَاللَّهِ لَتُعْطِيَنَّهُ وَرِقَهُ أَوْ لَتَرُدَّنَّ إِلَيْهِ ذَهَبَهُ فَإِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ الْوَرِقُ بِالذَّهَبِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالْبُرُّ بِالْبُرِّ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلاَّ هَاءَ وَهَاءَ. قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ. وَالْعَمَلُ عَلَى هَذَا عِنْدَ أَهْلِ الْعِلْمِ وَمَعْنَى قَوْلِهِ إِلاَّ هَاءَ وَهَاءَ يَقُولُ يَدًا بِيَدٍ.
Mālik Ibn-Aws Ibnul-Ḥadathān narrated, "I showed up asking, 'Who here exchanges dirhams (1)?' Ṭalḥah Ibn-'Ubaydullāh, who was with 'Umar Ibnul-Khaṭṭāb at the time, replied, 'Give us your gold (now), and come back to us when our servant is here so that we give you your dirhams.' 'Umar Ibnul-Khaṭṭāb interjected, 'No! By God, you will either give him his dirhams (immediately) or return his gold, for the Messenger of God, peace and blessings of God be upon him, said, "The exchange of gold for dirhams is interest, unless it is done on the spot; the exchange of wheat for wheat is interest, unless it is done on the spot; the exchange of barley for barley is interest, unless it is done on the spot; and the exchange of dates for dates is interest, unless it is done on the spot."'"
(1) The currency of the time, not to be confused with the unit of weight.
