Sura Āl-ʿImrān 3:104

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

wa-l-takun minkum ummatun yadʿūna ilā l-khayri wa-yaʾmurūna bil-maʿrūfi wa-yanhawna ʿani l-munkari wa-ūlāʾika humu l-mufliḥūna

Let there arise out of you a band of people inviting to all that is good, enjoining what is right, and forbidding what is wrong: They are the ones to attain felicity.
