Arabic (Original)
حَدَّثَنَا عَبْدُ الْوَهَّابِ بْنُ عَبْدِ الْمَجِيدِ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى عَنْ الْمُزَابَنَةِ قَالَ فَكَانَ نَافِعٌ يُفَسِّرُهَا الثَّمَرَةُ تُشْتَرَى بِخَرْصِهَا تَمْرًا بِكَيْلٍ مُسَمًّى إِنْ زَادَتْ فَلِي وَإِنْ نَقَصَتْ فَعَلَيَّ.
English Translation
Abd al-Wahhab ibn Abd al-Majid narrated to us, from Ayyub, from Nafi', from Ibn Umar, that the Messenger of God, peace and blessings be upon him, forbade muzabanah. He said: Nafi' used to explain it as: fruit on the tree being bought by estimating its yield in dried dates by a stated measure - if it turns out more, it is mine, and if less, it is against me.
