ذِكْرُ الزَّجْرِ عَنْ بَيْعِ الصَّاعِ مِنَ التَّمْرِ بِالصَّاعَيْنِ وَإِنْ كَانَ أَحَدُهُمَا أَرْدَأَ مِنَ الْآخَرِ
some dates from trees that were irrigated artificially were brought to the Messenger of Allah and the dates of the messenger of Allah were dates from trees that were nourished by their roots. He said: "Where did you get these from?" They said: "We bought a Sa of them for two Sa s of our dates: He said: "Do not do that, for this is not right. Rather sell your dates and but what you need of these," (Using translation from Nasāʾī 4554)
أَنَّ رَسُولَ اللَّهِ ﷺ أُتِيَ بِتَمْرٍ رَيَّانَ وَكَانَ تَمْرُ رَسُولِ اللَّهِ ﷺ بَعْلًا فِيهِ يُبْسٌ فَقَالَ «أَنَّى لَكُمْ هَذَا؟ » قَالُوا ابْتَعْنَاهُ صَاعًا بِصَاعَيْنِ مِنْ تَمْرِنَا قَالَ «فَلَا تَفْعَلْ إِنَّ هَذَا لَا يَصْلُحُ وَلَكِنْ بِعْ تَمْرَكَ ثُمَّ اشْتَرِ مِنْ هَذَا حَاجَتَكَ»
