Surah Aali Imran (The Family of Imran), Verse 104

وَلْتَكُنْ مِّنْكُمْ اُمَّةٌ یَّدْعُوْنَ اِلَی الْخَیْرِ وَیَاْمُرُوْنَ بِالْمَعْرُوْفِ وَیَنْهَوْنَ عَنِ الْمُنْكَرِ وَاُولٰٓىِٕكَ هُمُ الْمُفْلِحُوْنَ ۟

Waltakum minkum ummatuny yad'oona ilal khairi wa ya'muroona bil ma'roofi wa yanhawna 'anil munkar; wa ulaaa'ika humul muflihoon

“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.”
