حَدَّثَنِي أَبُو الطَّاهِرِ، أَحْمَدُ بْنُ عَمْرِو بْنِ سَرْحٍ أَخْبَرَنَا ابْنُ وَهْبٍ، حَدَّثَنِي ابْنُ جُرَيْجٍ، أَنَّ أَبَا الزُّبَيْرِ، أَخْبَرَهُ قَالَ سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ بَيْعِ الصُّبْرَةِ مِنَ التَّمْرِ لاَ يُعْلَمُ مَكِيلَتُهَا بِالْكَيْلِ الْمُسَمَّى مِنَ التَّمْرِ ‏.‏
