Abu Huraira (Allah be pleased with him) reported that Messenger of Allah ﷺ deputed a person to collect revenue from Khaibar. He brought fine quality of dates, whereupon Messenger of Allah ﷺ said: Are all the dates of Khaibar like this)? He said: No. We got one sa' (of fine dates) for two sa's (of inferior dates), and (similarly) two sa's for three sa's. Thereupon Messenger of Allah ﷺ said: Don't do that rather sell the inferior quality of dates for dirhams (money), and then buy the superior quality with the help of dirhams.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ عَبْدِ الْمَجِيدِ بْنِ سُهَيْلِ بْنِ عَبْدِ، الرَّحْمَنِ بْنِ عَوْفٍ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، وَعَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ اسْتَعْمَلَ رَجُلاً عَلَى خَيْبَرَ فَجَاءَهُ بِتَمْرٍ جَنِيبٍ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ " أَكُلُّ تَمْرِ خَيْبَرَ هَكَذَا " . فَقَالَ لاَ وَاللَّهِ يَا رَسُولَ اللَّهِ إِنَّا لَنَأْخُذُ الصَّاعَ مِنْ هَذَا بِالصَّاعَيْنِ وَالصَّاعَيْنِ بِالثَّلاَثَةِ . فَقَالَ رَسُولُ اللَّهِ ﷺ " فَلاَ تَفْعَلْ بِعِ الْجَمْعَ بِالدَّرَاهِمِ ثُمَّ ابْتَعْ بِالدَّرَاهِمِ جَنِيبًا " .
