Al A’raf Ayah 85

وَإِلَىٰ مَدْيَنَ أَخَاهُمْ شُعَيْبًا‌ۗ قَالَ يَـٰقَوْمِ ٱعْبُدُواْ ٱللَّهَ مَا لَكُم مِّنْ إِلَـٰهٍ غَيْرُهُۥ‌ۖ قَدْ جَآءَتْكُم بَيِّنَةٌ مِّن رَّبِّكُمْ‌ۖ فَأَوْفُواْ ٱلْكَيْلَ وَٱلْمِيزَانَ وَلَا تَبْخَسُواْ ٱلنَّاسَ أَشْيَآءَهُمْ وَلَا تُفْسِدُواْ فِى ٱلْأَرْضِ بَعْدَ إِصْلَـٰحِهَا‌ۚ ذَٲلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُم مُّؤْمِنِينَ ٨٥ And to the people of Midian We sent their brother Shu’aib. He said, “O my people! Worship Allah—you have no other god except Him. A clear proof has already come to you from your Lord. So give just measure and weight, do not defraud people of their property, nor spread corruption in the land after it has been set in order. This is for your own good, if you are ?truly? believers.
