Surah 11. Hud
Ayah 84 - 86
84وَإِلَىٰ مَدْيَنَ أَخَاهُمْ شُعَيْبًا ۚ قَالَ يَـٰقَوْمِ ٱعْبُدُوا۟ ٱللَّهَ مَا لَكُم مِّنْ إِلَـٰهٍ غَيْرُهُۥ ۖ وَلَا تَنقُصُوا۟ ٱلْمِكْيَالَ وَٱلْمِيزَانَ ۚ إِنِّىٓ أَرَىٰكُم بِخَيْرٍ وَإِنِّىٓ أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ مُّحِيطٍ
85وَيَـٰقَوْمِ أَوْفُوا۟ ٱلْمِكْيَالَ وَٱلْمِيزَانَ بِٱلْقِسْطِ ۖ وَلَا تَبْخَسُوا۟ ٱلنَّاسَ أَشْيَآءَهُمْ وَلَا تَعْثَوْا۟ فِى ٱلْأَرْضِ مُفْسِدِينَ
86بَقِيَّتُ ٱللَّهِ خَيْرٌ لَّكُمْ إِن كُنتُم مُّؤْمِنِينَ ۚ وَمَآ أَنَا۠ عَلَيْكُم بِحَفِيظٍ
[84-86] And to the people of Madian, We sent their brother Shu`aib.94 He said. "O my people, serve Allah: you have no deity other than He. Do not give short measure and weight. Though I see you now in a state of prosperity, I fear for you the scourge of a day that will encircle you. And, O my people, give full measure and weight justly and do not defraud people of their goods, and do not spread mischief in the land. The residue (after giving full measure) left over by Allah is best for you, if you are believers. Anyhow I am not a guardian over you."95
94Please keep in view E.N.'s 69-76 of Al-A'araf.
95That is, "I have no power over you. The most I can do for you is to admonish you as a well-wisher, but it rests with you to accept my advice or reject it. As you are accountable to Allah and not to me for your deeds, therefore you should fear Him and desist from your mischievous deeds, if you sincerely believe in Him."
