to do. (Q.5:105) Scholars have provided a number of reasons why the obvious reading of this verse is incorrect, such as that it refers not to the present but "to some future time when forbidding wrong will cease to be effective." Hadith Appearing in Sahih Muslim, the second most prestigious collection of Sunni hadith is a famous report: 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". Mutazilite and Shia Imamis quote different traditions than this Sunni Hadith, but all agree on the Quran and on "the existence of the duty" to command and forbid. According to historian Michael Cook (whose book Commanding Right and Forbidding Wrong in Islamic Thought is the major English language source on the issue), a slightly different phrase is used in a similar hadith -- 'righting wrong' (taghyir al-munkar) instead of 'forbidding wrong' (an-nahy ʿani-l-munkar) -- but "scholars take it for granted" that 'the two "are the same thing, ..." Sunnis, Ibadis and Twelver (also called Imami) Shia schools of Islam "made extensive use of" the "schema" set out by this hadith Terminology Depending on the translation from the Quran, the phrase may also be translated as commanding what is just and forbidding what is evil, commanding right and forbidding wrong, and other combinations of "enjoin" or "command", "right" or "just", "wrong", "unjust", or "evil". Origins of "hisba" Sources give different meanings for Hisbah: "accountability", according to Sami Zubaida; based on either "retribution from God" or "seeking wages", according to Ibn Manzur; from the word ‘husban’, which means "calculation" according to Al-Zubaidiy. History Pre-Islamic Phrases similar to forbidding evil and commanding good can be found examining texts of the Ancient Greek philosophers -- Stoic Chrysippus (d.207 BC) and Aristotle (d.322) -- and the founder of Buddhism, Buddha. A particularly similar formulation is found in the book of Psalms: "Depart from evil, and do good; seek peace, and pursue it". (Psalm 34:14) However, Michael Cook finds no "serious precedent" for use of the phrases "forbidding wrong' (munkar) and "commanding right" (ma'ruf) in the literature of the immediate predecessors of Muhammad his companions, pre-Islamic Arabian traditions and poetry.
