وَعَنْ أَبِي سَعِيدٍ, وَأَبِي هُرَيْرَةَ -رَضِيَ اَللَّهُ عَنْهُمَا- { ;أَنَّ رَسُولَ اَللَّهِ - صلى الله عليه وسلم -اِسْتَعْمَلَ رَجُلًا عَلَى خَيْبَرٍ, فَجَاءَهُ بِتَمْرٍ جَنِيبٍ, فَقَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -أَكُلُّ تَمْرِ خَيْبَرَ هَكَذَا? فَقَالَ: لَا, وَاَللَّهِ يَا رَسُولَ اَللَّهِ, إِنَّا لَنَأْخُذُ اَلصَّاعَ مِنْ هَذَا بِالصَّاعَيْنِ وَالثَّلَاثَةِ [1] فَقَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم - لَا تَفْعَلْ، بِعِ اَلْجَمْعَ بِالدَّرَاهِمِ, ثُمَّ اِبْتَعْ بِالدَّرَاهِمِ جَنِيبًا } وَقَالَ فِي اَلْمِيزَانِ مِثْلَ ذَلِكَ. مُتَّفَقٌ عَلَيْهِ [2] .
Narrated Abu Sa'id al-Khudri and Abu Hurairah (RA): Allah's Messenger (ﷺ) appointed a man over Khaibar and he brought him dates of a very fine quality. Allah's Messenger (ﷺ) asked, "Are all the dates of Khaibar like this?" He replied, "I swear by Allah that they are certainly not, O Allah's Messenger (ﷺ) . We take one Sa' of this kind for two, and even for three (of lesser quality). So Allah's Messenger (ﷺ) said: "Do not do so. Sell the mixed dates for Dirhams, then buy the very fine dates with the Dirhams." And he said that the same applies when things are sold by weight. [Agreed upon].
