مُوَطَّأُ مَالِكٍ
Muwatta Malik 1316
Business Transactions
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ الْمُزَابَنَةِ وَالْمُزَابَنَةُ بَيْعُ الثَّمَرِ بِالتَّمْرِ كَيْلاً وَبَيْعُ الْكَرْمِ بِالزَّبِيبِ كَيْلاً .
Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, (ﷺ), forbade muzabana. Muzabana was selling fresh dates for dried dates by measure, and selling grapes for raisins by measure.
