We should never become obedient to and follow our nafs (carnal desire), or else with time we will become such slaves of our nafs that it will be very difficult to do any action contrary to the dictates of the nafs. On the other hand if we anger our nafs only for the pleasure of Allah Ta’ala and continue to place it under little difficulties (by abstaining from wrong), then it will automatically become accustomed to it. Then to carry out good deeds becomes very easy. For the friends of Allah Ta’ala, doing good actions is a total pleasure, whereas we find it very difficult. This is due to us always obeying our nafs, hence we desire to have ease and comfort at all times.
