Sahih Muslim , Book 21, Hadith 93 (In-Book) ⓘ
'Abdullah (b. Umar) reported that Allah's Apostle forbade Muzabana, i. e. buying of fresh dates (on) the trees for dry dates by measure, and the buying of grapes for raisins by measure and the selling of field of corn for corn by measure.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ، بِشْرٍ حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ، أَخْبَرَهُ أَنَّ النَّبِيَّ صلى الله عليه وسلم نَهَى عَنِ الْمُزَابَنَةِ بَيْعِ ثَمَرِ النَّخْلِ بِالتَّمْرِ كَيْلاً وَبَيْعِ الْعِنَبِ بِالزَّبِيبِ كَيْلاً وَبَيْعِ الزَّرْعِ بِالْحِنْطَةِ كَيْلاً .
