أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا خَالِدٌ، قَالَ حَدَّثَنَا هِشَامٌ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ بَيْعِ النَّخْلِ حَتَّى يُطْعَمَ .
It was narrated that Jabir said: "the Messenger of Allah forbade selling the fruit of date palms until they are fit to eat."
