How to rectify your heart....??

 

“If you want to rectify your heart, or want to see betterment in your child or companion—or whoever it is for that matter, then direct them to places where the Qurʾān is recited and direct them to be in the company of the Qurʾān. Allāh will then cause them to become better, whether they are willing to it or not.”

Imām ash-Shāfiʿī, in: Hilyat al-awliyāʾ 9/123.
