Zaid bin Thabit (ra) said, "In the lifetime of Messenger of Allah ﷺ, the people used to trade with fruits. When they cut their date-fruits and the purchasers came to recieve their rights, the seller would say, 'My dates have got rotten, they are blighted with disease, they are afflicted with Qusham (a disease which causes the fruit to fall before ripening).' They would go on complaining of defects in their purchases. Messenger of Allah ﷺ said, "Do not sell the fruits before their benefit is evident (i.e. free from all the dangers of being spoiled or blighted), by way of advice for they quarrelled too much." Kharija bin Zaid bin Thabit said that Zaid bin Thabit (ra) used not to sell the fruits of his land till Pleiades appeared and one could distinguish the yellow fruits from the red (ripe) ones.
كَانَ النَّاسُ فِي عَهْدِ رَسُولِ اللَّهِ ﷺ يَتَبَايَعُونَ الثِّمَارَ فَإِذَا جَدَّ النَّاسُ وَحَضَرَ تَقَاضِيهِمْ قَالَ الْمُبْتَاعُ إِنَّهُ أَصَابَ الثَّمَرَ الدُّمَانُ أَصَابَهُ مُرَاضٌ أَصَابَهُ قُشَامٌ عَاهَاتٌ يَحْتَجُّونَ بِهَا فَقَالَ رَسُولُ اللَّهِ ﷺ لَمَّا كَثُرَتْ عِنْدَهُ الْخُصُومَةُ فِي ذَلِكَ فَإِمَّا لاَ فَلاَ يَتَبَايَعُوا حَتَّى يَبْدُوَ صَلاَحُ الثَّمَرِ كَالْمَشُورَةِ يُشِيرُ بِهَا لِكَثْرَةِ خُصُومَتِهِمْ وَأَخْبَرَنِي خَارِجَةُ بْنُ زَيْدِ بْنِ ثَابِتٍ أَنَّ زَيْدَ بْنَ ثَابِتٍ لَمْ يَكُنْ يَبِيعُ ثِمَارَ أَرْضِهِ حَتَّى تَطْلُعَ الثُّرَيَّا فَيَتَبَيَّنَ الأَصْفَرُ مِنَ الأَحْمَرِ قَالَ أَبُو عَبْد اللَّهِ رَوَاهُ عَلِيُّ بْنُ بَحْرٍ حَدَّثَنَا حَكَّامٌ حَدَّثَنَا عَنْبَسَةُ عَنْ زَكَرِيَّاءَ عَنْ أَبِي الزِّنَادِ عَنْ عُرْوَةَ عَنْ سَهْلٍ عَنْ زَيْدٍ
