The Promised Messiah (as) states: “It is mentioned in the Holy Quran:
قَدۡ اَفۡلَحَ مَنۡ زَكّٰهَا
Meaning, one who purifies their soul has found salvation. To purify one’s soul, seek the company of the righteous, or fostering a relationship with those who are pious and virtuous is very beneficial. One ought to shun ignoble morals such as falsehood and the like, and seek guidance from one who already treads this path. One ought to correct their errors along the way. Just as one cannot improve their writing without identifying one’s mistakes, so too morals cannot be rectified until one identifies their errors. Man is the sort of creature that remains on the right path only if he is purified continuously as he goes along, otherwise he will deviate.”
