At the battle of Khaibar I bought a necklace in which there were gold and pearls for twelve dinars. I separated them and found that its worth was more than twelve dinars. So I mentioned that to the Prophet ﷺ who said: It must not be sold till the contents are considered separately. (Using translation from Abū Dāʾūd 3352)  

اشْتَرَيْتُ يَوْمَ خَيْبَرَ قِلَادَةً فِيهَا ذَهَبٌ وَخَرَزٌ فَفَصَّلْتُهَا فَوَجَدْتُ فِيهَا أَكْثَرَ مِنِ اثْنَيْ عَشَرَ دِينَارًا فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ «لَا تُبَاعُ حَتَّى تُفَصَّلَ»  

"On the Day of Khaibar I got a necklace containing gold and gems, and I wanted to sell it. Mention of that was made to the Prophet and he said: 'Take it apart, and then sell it."' (Using translation from Nasāʾī 4574)   

أَصَبْتُ يَوْمَ خَيْبَرَ قِلَادَةً فِيهَا ذَهَبٌ وَخَرَزٌ فَأَرَدْتُ بَيْعَهَا فَذَكَرْتُ يَعْنِي لِلنَّبِيِّ ﷺ فَقَالَ «افْصِلْ بَعْضَهَا مِنْ بَعْضٍ ثُمَّ بِعْهَا»
