Al-Mutaffifin 83:3

<h2>Which was revealed in Al-Madinah</h2><p>بِسْمِ اللَّهِ الرَّحْمَـنِ الرَّحِيمِ</p><p>In the Name of Allah, the Most Gracious, the Most Merciful.</p><h2>Increasing and decreasing in the Measure and Weight will be a Cause for Regret and Loss</h2><p>An-Nasa'i and Ibn Majah both recorded from Ibn `Abbas that he said, "When the Prophet came to Al-Madinah, the people of Al-Madinah were the most terrible people in giving measurement (i.e., they used to cheat). Thus, Allah revealed,</p><p>وَيْلٌ لِّلْمُطَفِّفِينَ</p><p>(Woe to Al-Mutaffifin.) After this, they began to give good measure." The meaning of the word Tatfif here is to be stingy with measurement and weight, either by increasing it if it is due from the others, or decreasing it if it is a debt. Thus, Allah explains that the Mutaffifin those whom He has promised loss and destruction, whom are meant by "Woe" are</p><p>الَّذِينَ إِذَا اكْتَالُواْ عَلَى النَّاسِ</p><p>(Those who, when they have to receive by measure from men,) meaning, from among the people.</p><p>يَسْتَوْفُونَ</p><p>(demand full measure,) meaning, they take their right by demanding full measure and extra as well.</p><p>وَإِذَا كَالُوهُمْ أَوْ وَّزَنُوهُمْ يُخْسِرُونَ</p><p>(And when they have to give by measure or weight to (other) men, give less than due.) meaning, they decrease. Verily, Allah commanded that the measure and weight …

But if they measure unto them or weight for them, they cause them loss.

But when they have to give by measure or weight to men, give less than due.

And when they have to give by measure or weight to men, give less than due.

But when they measure or weigh to others, they cheat.
