We were with the Messenger of Allah ﷺ at the battle of Khaibar. We were selling to the Jews one uqiyah of gold for one dinar. The narrators other than Qutaibah said: "for two or three dinars." Then both the versions agreed. The Messenger of Allah ﷺ said: Do not sell gold except with equal weight.  

أبو داود:٣٣٥٣ – حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا اللَّيْثُ عَنِ ابْنِ أَبِي جَعْفَرٍ عَنِ الْجُلاَحِ أَبِي كَثِيرٍ حَدَّثَنِي حَنَشٌ الصَّنْعَانِيُّ عَنْ فَضَالَةَ بْنِ عُبَيْدٍ قَالَ

كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ يَوْمَ خَيْبَرَ نُبَايِعُ الْيَهُودَ الأُوقِيَّةَ مِنَ الذَّهَبِ بِالدِّينَارِ قَالَ غَيْرُ قُتَيْبَةَ بِالدِّينَارَيْنِ وَالثَّلاَثَةِ ثُمَّ اتَّفَقَا فَقَالَ قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَبِيعُوا الذَّهَبَ بِالذَّهَبِ إِلاَّ وَزْنًا بِوَزْنٍ
