Surah Hud · Ayah 84

۞ وَإِلَىٰ مَدْيَنَ أَخَاهُمْ شُعَيْبًۭا ۚ قَالَ يَٰقَوْمِ ٱعْبُدُوا۟ ٱللَّهَ مَا لَكُم مِّنْ إِلَٰهٍ غَيْرُهُۥ ۖ وَلَا تَنقُصُوا۟ ٱلْمِكْيَالَ وَٱلْمِيزَانَ ۚ إِنِّىٓ أَرَىٰكُم بِخَيْرٍۢ وَإِنِّىٓ أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍۢ مُّحِيطٍۢ

Wa ilaa Madyana akhaahum Shu'aibaa; qaala yaa qawmi' budul laaha maa lakum min ilaahin ghairuhoo wa laa tanqusul mikyaala walmeezaan; inneee araakum bikhairinw wa innee akhaafu 'alaikum 'azaaba Yawmim muheet

And to Madyan [We sent] their brother Shu'ayb. He said, "O my people, worship Allah; you have no deity other than Him. And do not decrease from the measure and the scale. Indeed, I see you in prosperity, but indeed, I fear for you the punishment of an all-encompassing Day.
