Virtue is power!

This idea of man as an individuality of infinite power determines, according to the teachings of Islam, the worth of all human action. That which intensifies the sense of individuality in man is good, that which enfeebles it is bad. Virtue is power, force, strength; evil is weakness. Give man a keen sense of respect for his own personality, let him move fearless and free in the immensity of God’s earth, and he will respect the personalities of others and become perfectly virtuous.
(Islam as Moral & Political Ideal by Allama Iqbal)
