Muawiyah sold a cup of gold or silver for more than its weight. Abu Ad-Darda' said: "I heard the Messenger of Allah forbid such transactions unless it was like for like."
أَنَّ مُعَاوِيَةَ بَاعَ سِقَايَةً مِنْ ذَهَبٍ أَوْ وَرِقٍ بِأَكْثَرَ مِنْ وَزْنِهَا فَقَالَ أَبُو الدَّرْدَاءِ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَنْهَى عَنْ مِثْلِ هَذَا إِلاَّ مِثْلاً بِمِثْلٍ
[Machine] Muawiyah bought a cup made of silver for a price that was less than or equal to its value. Abu Darda said that the Messenger of Allah ﷺ forbade such transactions except if it is like for like.
أَنَّ مُعَاوِيَةَ اشْتَرَى سِقَايَةً مِنْ فِضَّةٍ بِأَقَلَّ مِنْ ثَمَنِهَا أَوْ أَكْثَرَ قَالَ فَقَالَ أَبُو الدَّرْدَاءِ نَهَى رَسُولُ اللهِ ﷺ عَنْ مِثْلِ هَذَا إِلَّا مِثْلًا بِمِثْلٍ
Muawiyah sold a cup of gold or silver for more than its weight. Abu Ad-Darda' said: "I heard the Messenger of Allah forbid such transactions unless it was like for like." (Using translation from Nasāʾī 4572)
أَنَّ مُعَاوِيَةَ بَاعَ سِقَايَةً مِنْ ذَهَبٍ أَوْ وَرِقٍ بِأَكْثَرَ مِنْ وَزْنِهَا فَقَالَ أَبُو الدَّرْدَاءِ سَمِعْتُ رَسُولَ اللهِ ﷺ يَنْهَى عَنْ مِثْلِ هَذَا إِلَّا مِثْلًا بِمِثْلٍ
