لَمَّا قَدِمَ النَّبِيُّ ـ صلى الله عليه وسلم ـ الْمَدِينَةَ كَانُوا مِنْ أَخْبَثِ النَّاسِ كَيْلاً فَأَنْزَلَ اللَّهُ سُبْحَانَهُ {وَيْلٌ لِلْمُطَفِّفِينَ} فَأَحْسَنُوا الْكَيْلَ بَعْدَ ذَلِكَ .
It was narrated that Ibn 'Abbas said:
"When the Prophet (ﷺ) came to Al-Madinah, they were the worst people in weights and measures. 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.
