Selling a necklace in which there are pearls and gold
Sahih Muslim
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، عَنِ ابْنِ أَبِي جَعْفَرٍ، عَنِ الْجُلاَحِ أَبِي كَثِيرٍ، حَدَّثَنِي حَنَشٌ الصَّنْعَانِيُّ، عَنْ فَضَالَةَ بْنِ عُبَيْدٍ، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم يَوْمَ خَيْبَرَ نُبَايِعُ الْيَهُودَ الْوُقِيَّةَ الذَّهَبَ بِالدِّينَارَيْنِ وَالثَّلاَثَةِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ تَبِيعُوا الذَّهَبَ بِالذَّهَبِ إِلاَّ وَزْنًا بِوَزْنٍ " .
Fadala b. 'Ubaid reported: We were in the company of Allah's Messenger ( may peace be upon him) on the day (of the Victory of) Khaibar, and made transaction with the Jews for the 'uqiya of gold for the dinars or three (gold coins), whereupon Allah's Messenger (ﷺ) said: Do not sell gold for gold but for equal weight
