The Book of Transactions
21/14. Chapter:
The prohibition of selling fresh dates in exchange for dry dates except in the case of 'Araya
Sahih Muslim
وَحَدَّثَنَا مُحَمَّدُ بْنُ رُمْحِ بْنِ الْمُهَاجِرِ، حَدَّثَنَا اللَّيْثُ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، حَدَّثَنِي زَيْدُ بْنُ ثَابِتٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَخَّصَ فِي بَيْعِ الْعَرِيَّةِ بِخَرْصِهَا تَمْرًا . قَالَ يَحْيَى الْعَرِيَّةُ أَنْ يَشْتَرِيَ الرَّجُلُ ثَمَرَ النَّخَلاَتِ لِطَعَامِ أَهْلِهِ رُطَبًا بِخَرْصِهَا تَمْرًا .
Zaid b Thabit (Allah be pleased with him) reported that Allah's Messenger (ﷺ) gave concession in case of al-'ariyya transactions (for exchanging dates) for dates with measure. Yahya said: 'Ariyya implies that a person should buy fresh dates on the tree for his family to eat against a measure of dry dates.
