وَعَنْ سَهْلِ بْنِ أَبِي حَثْمَةَ
قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَن بيعِ التمْر بالتمْرِ إِلَّا أَنَّهُ رَخَّصَ فِي الْعَرِيَّةِ أَنْ تُبَاعَ بِخَرْصِهَا تَمْرًا يَأْكُلُهَا أَهْلُهَا رُطَبًا
God’s Messenger forbade the sale of fruit for dried dates but gave licence regarding the ariya for its sale on the basis of a calculation of what the dates would be when dry, yet those who bought them could eat them when fresh.
