Compiled by Imam Muslim ibn al-Hajjaj
وَحَدَّثَنِي عَلِيُّ بْنُ حُجْرٍ السَّعْدِيُّ، وَزُهَيْرُ بْنُ حَرْبٍ، قَالاَ حَدَّثَنَا إِسْمَاعِيلُ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ بَيْعِ النَّخْلِ حَتَّى يَزْهُوَ وَعَنِ السُّنْبُلِ حَتَّى يَبْيَضَّ وَيَأْمَنَ الْعَاهَةَ نَهَى الْبَائِعَ وَالْمُشْتَرِيَ .
Ibn 'Umar (Allah be pleased with them) reported that Allah's Messenger (ﷺ) forbade the sale of palm-trees (i. e. their trults) until the dates began to ripen, and ears of corn until they were white and were safe from blight. He forbade the seller and the buyer.
