'Ariyyah means that a man gives another man a palm-tree on loan, or it means that reserves one or two palm-trees from his property for his personal use, then he sells for dried dates. (Using translation from Abū Dāʾūd 3365)
أَنَّهُ قَالَ الْعَرِيَّةُ الرَّجُلُ يُعْرِي الرَّجُلَ النَّخْلَةَ أَوِ الرَّجُلُ يَسْتَثْنِي مِنْ مَالِهِ النَّخْلَةَ أَوِ الِاثْنَتَيْنِ لِيَأْكُلَهَا فَيَبِيعَهَا بِتَمْرٍ
