حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ بِشْرِ بْنِ الْحَكَمِ، وَمُحَمَّدُ بْنُ عَقِيلِ بْنِ خُوَيْلِدٍ، قَالاَ حَدَّثَنَا عَلِيُّ بْنُ الْحُسَيْنِ بْنِ وَاقِدٍ، حَدَّثَنِي أَبِي، حَدَّثَنِي يَزِيدُ النَّحْوِيُّ، أَنَّ عِكْرِمَةَ، حَدَّثَهُ عَنِ ابْنِ عَبَّاسٍ، قَالَ لَمَّا قَدِمَ النَّبِيُّ ـ صلى الله عليه وسلم ـ الْمَدِينَةَ كَانُوا مِنْ أَخْبَثِ النَّاسِ كَيْلاً فَأَنْزَلَ اللَّهُ سُبْحَانَهُ {وَيْلٌ لِلْمُطَفِّفِينَ} فَأَحْسَنُوا الْكَيْلَ بَعْدَ ذَلِكَ .

Then Allah, Glorious is He revealed: "Woe to the Mutaffifun (those who give less in measure and weight)",[1] and they were fair in weights and measures after that. Translation Not Available
