Since you have been empowered by the Qur'an, you are the best suited Community that has been raised up for the good of mankind. It is your duty to enjoin the Right and forbid the Wrong, since you accept the Final Word of God as the Criterion (3:4). The Qur'an clearly educates you on the Permanent Moral Value System and decrees authoritatively what the otherwise vague terms of 'right' and 'wrong', and 'good' and 'evil' might mean. Now if the People of the Scripture had attained this kind of belief, it would have been for their own good. But only few among them are believers, while most of them are drifting away from the Truth.
