Al-A'raf 7:85
وَإِلَىٰ مَدْيَنَ أَخَاهُمْ شُعَيْبًا ۗ قَالَ يَـٰقَوْمِ ٱعْبُدُوا۟ ٱللَّهَ مَا لَكُم مِّنْ إِلَـٰهٍ غَيْرُهُۥ ۖ قَدْ جَآءَتْكُم بَيِّنَةٌ مِّن رَّبِّكُمْ ۖ فَأَوْفُوا۟ ٱلْكَيْلَ وَٱلْمِيزَانَ وَلَا تَبْخَسُوا۟ ٱلنَّاسَ أَشْيَآءَهُمْ وَلَا تُفْسِدُوا۟ فِى ٱلْأَرْضِ بَعْدَ إِصْلَـٰحِهَا ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُم مُّؤْمِنِينَ

And to [the people of] Madyan [We sent] their brother Shuʿayb. He said, "O my people, worship Allāh; you have no deity other than Him. There has come to you clear evidence from your Lord. So fulfill the measure and weight and do not deprive people of their due and cause not corruption upon the earth after its reformation. That is better for you, if you should be believers.
And to Madyan (We sent) their brother Shu‘aib. He said, “O my people, worship Allah. You have no god other than Him. There has come to you a clear sign from your Lord. Give the measure and weight in full, and do not make people short of their things, and do not make mischief on the earth after it has been set in order. That is good for you, if you are believers.
