Question:
What should I do if an old sin is afflicting me by counterproductive thinking about it cause I obsess about this thinking. I feel this counterproductive thinking about this sin is killing my passion for Islam and my love to ALLAH and His messenger (peace upon him)What should I do to give this counterproductive thinking up (and the obsess about it)and to win back the strong love and passion to ALLAH, Islam and to his messenger? (peace upon him)
Answer:
For every recurring memory of it just humbly renew your istighfar. Our sins are not an important idol but a stairwell for building repentance and affirming our lowliness before the All-Forgiving and draw nearer and nearer to Him.
