Sahih Muslim 1539
Sahih Muslim · Book 21: The Book of Transactions · The prohibition of selling fresh dates in exchange for dry dates except in the case of 'Araya
وَحَدَّثَنَا أَبُو الرَّبِيعِ ، وَأَبُو كَامِلٍ قَالاَ حَدَّثَنَا حَمَّادٌ ، ح وَحَدَّثَنِيهِ عَلِيُّ بْنُ حُجْرٍ ، حَدَّثَنَا إِسْمَاعِيلُ ، كِلاَهُمَا عَنْ أَيُّوبَ ، عَنْ نَافِعٍ ، بِهَذَا الإِسْنَادِ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَخَّصَ فِي بَيْعِ الْعَرَايَا بِخَرْصِهَا .
Nafi, reported this hadith with the same chain of transmitters stating that Allah's Messengtr (ﷺ) granted concession in case of 'ariyya transactions (for exchange of the same commodity) with measure.
