Hadith 8:77
Abu Huraira said God's Messenger gave licence regarding the sale of ‘araya for a computation of their amount when dry, provided they were less than five wasqs *, or amounted to five wasqs . Dawud b. al Husain was doubtful [which he said.] (Bukhari and Muslim.) *( wasq is a camel load=60 sa’s )
وَعَنْ أَبِي هُرَيْرَةَ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَرْخَصَ فِي بَيْعِ الْعَرَايَا بِخَرْصِهَا مِنَ التَّمْرِ فِيمَا دُونَ خَمْسَة أوسق أَو خَمْسَة أوسق شكّ دَاوُد ابْن الْحصين
