Amr bil-Ma'ruf wa Nahi 'an al-Munkar (Commanding Good and Forbidding Evil)

وَلْتَكُن مِّنكُمْ أُمَّةٌ يَدْعُونَ إِلَى ٱلْخَيْرِ وَيَأْمُرُونَ بِٱلْمَعْرُوفِ وَيَنْهَوْنَ عَنِ ٱلْمُنكَرِ ۚ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ

And let there be [arising] from you a nation inviting to [all that is] good, enjoining what is right and forbidding what is wrong, and those will be the successful.
