Narrated Zaid bin Thabit:
حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ ، حَدَّثَنَا سُفْيَانُ ، عَنْ يَحْيَى بْنِ سَعِيدٍ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ، عَنْ زَيْدِ بْنِ ثَابِتٍ ـ رضى الله عنهم ـ قَالَ رَخَّصَ النَّبِيُّ صلى الله عليه وسلم أَنْ تُبَاعَ الْعَرَايَا بِخَرْصِهَا تَمْرًا.
The Prophet (ﷺ) permitted selling the dates of the 'Araya for ready dates by estimating the amount of the former (as they are still on the trees).
