وَعَنْ أَبِي هُرَيْرَةَ رضى الله عنه
«أَنَّ رَسُولَ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَخَّصَ فِي بَيْعِ اَلْعَرَايَا بِخَرْصِهَا، فِيمَا دُونَ خَمْسَةِ أَوْسُقٍ، أَوْ فِي خَمْسَةِ أَوْسُقٍ»
The Messenger of Allah (sallallahu alayhi wa sallam) gave permission regarding the sale of al-Araya, on the basis of calculation of their amount, for dry dates, on the condition that they be less than five Awsuq, or amounting to five Awsuq.
