It is ordered through this verse that there should always be a group among Muslims who enjoin goodness and forbid evil. Then the verse concludes that success and prosperity can only be attained in that way. Our reverend prophet, by a parable, makes clear the importance of enjoyining righteousness and forbidding evil. He said: ``A wrong doer among the population is like a traveller among a group of other passengers who are all sailing on a ship. When their ship is sailing midway on the sea, the traveller takes an axe and scuttles the ship! If the other passengers do not forbid him digging holes on the deck, sooner or later the ship will sink and all the crews will drown.''
