وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، أَنَّ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ، بَاعَ سِقَايَةً مِنْ ذَهَبٍ أَوْ وَرِقٍ بِأَكْثَرَ مِنْ وَزْنِهَا فَقَالَ أَبُو الدَّرْدَاءِ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَنْهَى عَنْ مِثْلِ هَذَا إِلاَّ مِثْلاً بِمِثْلٍ ‏.‏ فَقَالَ لَهُ مُعَاوِيَةُ مَا أَرَى بِمِثْلِ هَذَا بَأْسًا ‏.‏ فَقَالَ أَبُو الدَّرْدَاءِ مَنْ يَعْذِرُنِي مِنْ مُعَاوِيَةَ أَنَا أُخْبِرُهُ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم وَيُخْبِرُنِي عَنْ رَأْيِهِ لاَ أُسَاكِنُكَ بِأَرْضٍ أَنْتَ بِهَا ‏.‏ ثُمَّ قَدِمَ أَبُو الدَّرْدَاءِ عَلَى عُمَرَ بْنِ الْخَطَّابِ فَذَكَرَ ذَلِكَ لَهُ فَكَتَبَ عُمَرُ بْنُ الْخَطَّابِ إِلَى مُعَاوِيَةَ أَنْ لاَ تَبِيعَ ذَلِكَ إِلاَّ مِثْلاً بِمِثْلٍ وَزْنًا بِوَزْنٍ ‏.‏
