Hadith 2838
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
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)
