Enjoining what is right and forbidding what is wrong (Arabic: الأمر بالمَعْرُوف والنَهي عن المُنْكَر, romanized: al-amr bi-l-maʿrūf wa-n-nahy ʿani-l-munkar) are two important Islamic requisites from the Quran, "you enjoin what is right and forbid what is reprehensible", and are considered positive roles in helping others to take the straight path and abstain from reprehensible acts.
Ye are the best of peoples, evolved for mankind, enjoining what is right, forbidding what is wrong, and believing in Allah. 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.
You are the best community that has been raised up for mankind: You enjoin What is right and forbid What is evil, and You believe in Allah; if the people of the scripture deary it, it had been better for them, some of them believers, but most of them are evil-livers.
Abu Sa‘id al-Khudri reported that the prophet Muhammad said, "Whoever amongst you sees an evil, he must change it with his hand. If he is not able to do so, then with his tongue. And if he is not able to do so, then with his heart, and that is the weakest form of faith".
A standard medieval interpretation of this Hadith is, as Al-Nawawi had explained, that such passages of scripture had to be interpreted in accordance with established Shariah principles, such as the state's sole prerogative in declaring jihad. 'Changing the reprehensible by hand,' or by compulsion, was the purview of the state alone. 'Changing with the tongue' was the right of the ulama. Ordinary, individual Muslims should only reject the reprehensible with their hearts.
A person should have knowledge of what is considered wajib (obligatory or duty) and haram (sinful or forbidden) in relation to interpreting the two requisites although in a broad-spectrum.
