"Zaid bin Thabit told me that the Messenger of Allah ﷺ gave a concession regarding the sale of the estimated harvest of 'Araya return for dried dates." (Sahih) Yahya (one of the narrators) said: "The 'Araya is when a man purchases dates on the trees for food that his family has that is ripe, by estimating them (the dates)."
أَنَّ رَسُولَ اللَّهِ ﷺ أَرْخَصَ فِي بَيْعِ الْعَرِيَّةِ بِخَرْصِهَا تَمْرًا قَالَ يَحْيَى الْعَرِيَّةُ أَنْ يَشْتَرِيَ الرَّجُلُ ثَمَرَ النَّخَلاَتِ بِطَعَامِ أَهْلِهِ رُطَبًا بِخَرْصِهَا تَمْرًا
