أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ يَحْيَى، عَنْ بُشَيْرِ بْنِ يَسَارٍ، عَنْ سَهْلِ بْنِ أَبِي حَثَمَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم نَهَى عَنْ بَيْعِ الثَّمَرِ حَتَّى يَبْدُوَ صَلاَحُهُ وَرَخَّصَ فِي الْعَرَايَا أَنْ تُبَاعَ بِخَرْصِهَا يَأْكُلُهَا أَهْلُهَا رُطَبًا ‏.‏

It was narrated from Sahl bin Abi Hathamah that the Prophet forbade selling fruits before their condition was known, but he granted a concession allowing 'Araya sales by estimate, so its people could eat fresh dates. Translation Not Available
