Enjoining (what is) right and forbidding (what is) evil () are two important duties imposed by God in Islam, as revealed in the Quran and hadith. This expression is the base of the Islamic institution of hisbah (the individual or collective duty – depending on the Islamic school of law – to intervene and enforce Islamic law). It forms a central part of the Islamic doctrine for all Muslims. The injunctions also constitute two of the ten Ancillaries or Obligatory Acts of Twelver Shia Islam. Pre-modern Islamic literature describes pious Muslims (usually scholars) taking action to forbid wrong by destroying forbidden objects, particularly liquor and musical instruments. In the contemporary Muslim world, various state or parastatal bodies (often with phrases like the "Promotion of Virtue and the Prevention of Vice" in their titles) have appeared in Iran, Saudi Arabia, Nigeria, Sudan, Malaysia, etc., at various times and with various levels of power. Scriptural basis Answering the question of why there is a duty among Muslims to forbid wrong are statements in the Quran and hadith.

If only the People of the Book had faith, it were best for them: among them are some who have faith, but most of them are transgressors. -- Quran 3:110 translated by Abdullah Yusuf Ali The believers, both men and women, are guardians of one another. They encourage good and forbid evil, establish prayer and pay alms-tax, and obey Allah and His Messenger... (Q.9:71) ˹It is the believers˺ who repent, who are devoted to worship, who praise ˹their Lord˺, who fast, who bow down and prostrate themselves, who encourage good and forbid evil, and who observe the limits set by Allah... (Q.9:112) “O people! Establish prayer, encourage what is good and forbid what is evil, and endure patiently whatever befalls you. (Q.31:17) O you who have believed, upon you is [responsibility for] yourselves. Those who have gone astray will not harm you when you have been guided. To Allāh is your return all together; then He will inform you of what you used
