"The (true) believers are only those who believe in Allah and his messenger and afterward doubt not, but strive with their wealth and their selves for the cause of Allah. Such are the truthful." 49:15
Muslims should remove tyranny, treachery, bigotry, and ignorance and replace them with justice and equity. We should provide truthful knowledge and free people from the bondage of associationism (shirk or multiple gods), prejudice, superstition and mythology. Muslims remove immorality, fear, crime, exploitation and replace them with divine morality, peace and education.
