In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Staying within the boundaries of Halaal and Haraam, and not coming close to the doubtful matters depends on the righteousness or corruption of a person’s heart. If the heart has [ الورع – apprehensive fear (Ref1)] and Taqwah (piety), it will distance itself from haraam and that which will lead to Haraam. However, if the heart is corrupt, it will not be bothered about falling into (error).
If the sickness in the heart is not severe, the heart gets involved in the doubtful matters; and if the sickness increases, the heart gets involved in Haraam.
If the corruption is very severe, the heart will not be safeguarded against what is forbidden, and if the corruption is not severe, the heart will not be safeguarded against the doubtful matters. This shows the importance of rectification of the heart. [Ref 2]
