Jabir b. Abdullah (Allah be pleased with them) is reported to have said that Messenger of Allah ﷺ forbade the sale of a heap of dates the weight of which is unknown in accordance with the known weight of dates.  

أَخْبَرَهُ قَالَ سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ يَقُولُ نَهَى رَسُولُ اللَّهِ ﷺ عَنْ بَيْعِ الصُّبْرَةِ مِنَ التَّمْرِ لاَ يُعْلَمُ مَكِيلَتُهَا بِالْكَيْلِ الْمُسَمَّى مِنَ التَّمْرِ  

This hadith is narrated on the authority of Jabir b. Abdullah (Allah be pleased with them) but with this variation that no mention is made of the dates (which one finds) at the end of the previous hadith.  

أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ يَقُولُ نَهَى رَسُولُ اللَّهِ ﷺ بِمِثْلِهِ غَيْرَ أَنَّهُ لَمْ يَذْكُرْ مِنَ التَّمْرِ فِي آخِرِ الْحَدِيثِ
