وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ دَاوُدَ بْنِ الْحُصَيْنِ، عَنْ أَبِي سُفْيَانَ، مَوْلَى ابْنِ أَبِي أَحْمَدَ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ الْمُزَابَنَةِ وَالْمُحَاقَلَةِ وَالْمُزَابَنَةُ اشْتِرَاءُ الثَّمَرِ بِالتَّمْرِ فِي رُءُوسِ النَّخْلِ وَالْمُحَاقَلَةُ كِرَاءُ الأَرْضِ بِالْحِنْطَةِ ‏.‏
