The Prophet ﷺ gave license for the sale of 'araya for dried dates and fresh dates.  

أَنَّ النَّبِيَّ ﷺ رَخَّصَ فِي بَيْعِ الْعَرَايَا بِالتَّمْرِ وَالرُّطَبِ  

The Messenger of Allah ﷺ forbade the sale of fruits for dried dates, but gave license regarding the 'araya for its sale on the basis of a calculation of their amount. But those who buy them can eat them when fresh.  

أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنْ بَيْعِ الثَّمَرِ بِالتَّمْرِ وَرَخَّصَ فِي الْعَرَايَا أَنْ تُبَاعَ بِخَرْصِهَا يَأْكُلُهَا أَهْلُهَا رُطَبًا
