Question: What is the ruling on reporting on those who do mischief like drug dealers who want to disrupt the safety in the Muslim lands?
Answer: “This is obligatory, reporting on the people of evil whose danger is general to the Muslims and society. Whoever knows about them and knows their people, their places, and actions, then it is obligatory to report on them. This is because this is sincere advice for the Muslim rulers and their general folk. Yes”
