وَعَنِ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا
قَالَ: «نَهَى رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ بَيْعِ اَلثِّمَارِ حَتَّى يَبْدُوَ صَلَاحُهَا، نَهَى اَلْبَائِعَ وَالْمُبْتَاعَ»
The Messenger of Allah (sallallahu alayhi wa sallam) forbade the sale of fruits till they appear to ripe, forbidding it both to the seller and to the buyer.
