Sahih al-Bukhari 2170
حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ مَالِكِ بْنِ أَوْسٍ، سَمِعَ عُمَرَ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " الْبُرُّ بِالْبُرِّ رِبًا إِلاَّ هَاءَ وَهَاءَ، وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلاَّ هَاءَ وَهَاءَ، وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلاَّ هَاءَ وَهَاءَ ".
Abu al-Walid narrated to us: al-Layth narrated to us, from Ibn Shihab, from Malik ibn Aws, who heard Umar, may Allah be pleased with them both, report from the Prophet, who said: “Wheat for wheat is usury unless it is hand to hand; barley for barley is usury unless it is hand to hand; and dates for dates are usury unless they are hand to hand.”
Translation notes
The Arabic states the hand-to-hand condition. The witness adds that the quantities must be equal, which is not stated in this Arabic wording.
