Contentment is the greatest door that one enters to Allah, it is the source of tranquility for the worshiper and paradise on earth. Whoever does not enter it will not enter the Paradise in the Hereafter.
Ibn TaymiyyahHow many of us would be able to overcome our desires and resist the temptation of sin? How many of us even lower our gaze when we look upon something that we are not supposed to? The real prisoner is the one whose heart has been kept away from remembering his Lord, and the real captive is the one who has been captivated by his whims and desires.
Ibn TaymiyyahThe one who is [truly] imprisoned is the one whose heart is imprisoned from Allah and the captivated one is the one whose desires have enslaved him.
Ibn Taymiyyah
