Zaid b. Thabit (Allah be pleased with him) reported Messenger of Allah (may peace he upon him) having given concession in case of 'ariyya for selling dry dates (with) fresh dates after measuring them out. (Using translation from Muslim 1539c)
«أَنَّ رَسُولَ اللَّهِ ﷺ رَخَّصَ لِصَاحِبِ الْعَرِيَّةِ أَنْ يَبِيعَهَا بِخَرْصِهَا مِنَ التَّمْرِ»
