Forbidding Evil (Nahy 'an al-Munkar)

فَلَوْلَا كَانَ مِنَ ٱلْقُرُونِ مِن قَبْلِكُمْ أُو۟لُوا۟ بَقِيَّةٍ يَنْهَوْنَ عَنِ ٱلْفَسَادِ فِى ٱلْأَرْضِ إِلَّا قَلِيلًا مِّمَّنْ أَنجَيْنَا مِنْهُمْ ۗ وَٱتَّبَعَ ٱلَّذِينَ ظَلَمُوا۟ مَآ أُتْرِفُوا۟ فِيهِ وَكَانُوا۟ مُجْرِمِينَ

So why were there not among the generations before you those of enduring discrimination forbidding corruption on earth - except a few of those We saved from among them? But those who wronged pursued what luxury they were given therein, and they were criminals.

وَلَقَدْ قَالَ لَهُمْ هَـٰرُونُ مِن قَبْلُ يَـٰقَوْمِ إِنَّمَا فُتِنتُم بِهِۦ ۖ وَإِنَّ رَبَّكُمُ ٱلرَّحْمَـٰنُ فَٱتَّبِعُونِى وَأَطِيعُوٓا۟ أَمْرِى

And Aaron had already told them before [the return of Moses], "O my people, you are only being tested by it, and indeed, your Lord is the Most Merciful, so follow me and obey my order."
