Enjoining good (al-amr bi al-ma‘rūf) and forbidding evil (al-nahy ‘an al-munkar) are two acts of worship that every mature Muslim has to perform whenever applicable. No Muslim can be indifferent to what happens in the world around him. Part of the social responsibilities of each individual Muslim is to observe human and religious values, and whenever any of these values is deliberately overlooked or violated, he must advise and direct those responsible towards performing good and against committing bad and sinful acts (3:104, 110 & 114; 7:199; 9:71 & 112; 22:41).
