حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ ، حَدَّثَنَا مَالِكٌ ، ح وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى ، - وَاللَّفْظُ لَهُ - قَالَ قُلْتُ لِمَالِكٍ حَدَّثَكَ دَاوُدُ بْنُ الْحُصَيْنِ ، عَنْ أَبِي سُفْيَانَ ، - مَوْلَى ابْنِ أَبِي أَحْمَدَ - عَنْ أَبِي هُرَيْرَةَ ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَخَّصَ فِي بَيْعِ الْعَرَايَا بِخَرْصِهَا فِيمَا دُونَ خَمْسَةِ أَوْسُقٍ أَوْ فِي خَمْسَةِ - يَشُكُّ دَاوُدُ قَالَ خَمْسَةٌ أَوْ دُونَ خَمْسَةٍ - قَالَ نَعَمْ .
Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) having given exemption of 'ariyya transactions measuring less than five wasqs or up to five wasqs (the narrator Dawud is in doubt whether it was five or less than five).
