The Quran affords much importance to the nafs of an individual, highlighting the agency of free will and intelligence, without which neither responsibility nor accountability can exist. The Quran does not attribute to the nafs any inherent properties of good or evil, but instead conveys the idea that it is something which has to be nurtured and self-regulated, so that it can progress into becoming 'good' through its thoughts and actions. The Quranic conception of the nafs therefore has an extremely modernistic undertone, much like Nietzsche's conception of "Übermensch" or 'Superman', as suggested by Muhammad Iqbal, a prominent Muslim scholar and philosopher, who went as far as to accuse Nietzsche of borrowing the term from Islamic thought.
