Sunan Abi Dawud, Hadith 3408 ⓘ
Narrated Jabir ibn Abdullah: Ibn Rawahah assessed them (the amount of dates) at forty thousand wasqs, and when Ibn Rawahah gave them option, the Jews took the fruits in their possession and twenty thousand wasqs of dates were due from them.
حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، وَمُحَمَّدُ بْنُ بَكْرٍ، قَالاَ حَدَّثَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي أَبُو الزُّبَيْرِ، أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ خَرَصَهَا ابْنُ رَوَاحَةَ أَرْبَعِينَ أَلْفَ وَسْقٍ وَزَعَمَ أَنَّ الْيَهُودَ لَمَّا خَيَّرَهُمُ ابْنُ رَوَاحَةَ أَخَذُوا الثَّمَرَ وَعَلَيْهِمْ عِشْرُونَ أَلْفَ وَسْقٍ .
