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.
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 .
