The path espoused by the Quran and Sunnah for purifying one’s soul is amazingly very clear and actually easy to follow for all those whose intentions are pure. Indeed, it is a path that is open for every human to follow. It basically is comprised of three components:
(1) purification of one’s beliefs;
(2) drawing closer to Allah by performing the obligatory deeds and
(3) drawing even closer to Allah by the voluntary deeds.
