[Machine] Two men made a contract during the time of the Messenger of Allah ﷺ, regarding fresh dates and dried dates. The Messenger of Allah ﷺ asked, "Does the dried date decrease in weight when it becomes dry?" They replied, "Yes." He then said, "Then it is not permissible." This was narrated by Sufyan Ath-Thawri from Ismail bin Umayyah.
تَبَايَعَ رَجُلَانِ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ بِبُسْرٍ وَرُطَبٍ فَقَالَ رَسُولُ اللَّهِ ﷺ «هَلْ يَنْقُصُ الرُّطَبُ إِذَا يَبِسَ؟» قَالُوا نَعَمْ قَالَ «فَلَا إِذًا» وَهَكَذَا رَوَاهُ سُفْيَانُ الثَّوْرِيُّ عَنْ إِسْمَاعِيلَ بْنِ أُمَيَّةَ
