Al-Ma'idah' - 5:100

قُل لاَّ يَسْتَوِي الْخَبِيثُ وَالطَّيِّبُ وَلَوْ أَعْجَبَكَ كَثْرَةُ الْخَبِيثِ فَاتَّقُواْ اللّهَ يَا أُوْلِي الأَلْبَابِ لَعَلَّكُمْ تُفْلِحُونَ
[5:100]
Say: The bad and the good are not equal, though the abundance of the bad may please you; so be careful of (your duty to) Allah, O men of understanding, that you may be successful.
Say: "Not equal are things that are bad and things that are good, even though the abundance of the bad may dazzle thee; so fear Allah, O ye that understand; that (so) ye may prosper."
Say: The evil and the good are not alike even though the plenty of the evil attract thee. So be mindful of your duty to Allah, O men of understanding, that ye may succeed.
