(87) باب إِذَا بَاعَ الثِّمَارَ قَبْلَ أَنْ يَبْدُوَ صَلاَحُهَا ثُمَّ أَصَابَتْهُ عَاهَةٌ فَهُوَ مِنَ الْبَائِع
Narrated Ibn Shihab:
If somebody bought fruits before their benefit is evident and then the fruits were spoiled with blights, the loss would be suffered by the owner (not the buyer).Narrated Salim bin 'Abdullah from Ibn Umar: Allah's Messenger (ﷺ) said, "Donot sell or buy fruits before their benefit was evident and do not sell fresh fruits (dates) for dried dates."
