83:1-3
وَيْلٌ لِّلْمُطَفِّفِينَ الَّذِينَ إِذَا اكْتَالُوا عَلَى النَّاسِ يَسْتَوْفُونَ وَإِذَا كَالُوهُمْ أَو وَّزَنُوهُمْ يُخْسِرُونَ
“Woe to those who give less than due – who, when they take a measure from people, take it in full. But if they give by measure or by weight to them, they cause loss.”
The foundational Islamic teaching on commercial ethics – defrauding in weights and measures is not merely a regulatory offence but a spiritual crime meriting divine condemnation.
83:26
خِتَامُهُ مِسْكٌ وَفِي ذَٰلِكَ فَلْيَتَنَافَسِ الْمُتَنَافِسُونَ
“Its end is musk – and for that let the competitors compete.”
The divine invitation to compete for the highest – the pure drink sealed with musk in Paradise is the only prize worth racing toward, reorienting human ambition from worldly competition to spiritual striving.
