وَيۡلٌ لِّلۡمُطَفِّفِينَ (١) ٱلَّذِينَ إِذَا ٱكۡتَالُواْ عَلَى ٱلنَّاسِ يَسۡتَوۡفُونَ(٢) وَإِذَا كَالُوهُمۡ أَوْ وَّزَنُوهُمۡ يُخۡسِرُونَ (٣)(سورۃ المطففین)
Translation
Great ruin is for those who give less in measure and weight, (1) whose condition is that when they themselves take something by measure from people, they take it fully, (2) and when they give to someone by measure or by weight, they give less (3). (Asan Tarjuma-ul-Quran)
