Answered by Shaykh Faraz Rabbani
A Muslim girl feels lots of resentment and grudge towards a Muslim guy because of things he said to her in the past (they shouldn’t have been talking in the first place). But this girl finds pleasuring in knowing that he is still doing haram things (i.e.: talking to non mahram girls on the phone) while this girl has repented. She finds satisfaction with herself that she is not doing such things. Is this bad? How can one go about to correct these feelings? There is no way that this girl will talk to the guy and tell him to correct his behavior. What is the least she can do?
Such feelings are very blameworthy.
The Prophet (Allah bless him & give him peace) said, “None of you [truly] believes until he love s f or his brother that which he love s f or himself.”
The most essential of these matters we love for others is belief and obedience to Allah: we must wish for all to be fir m in belief and steadfast in obedience to Allah.
Whenever a bad though occurs about that brother, the sister in question should make a heart-felt dua to Allah for the brother’s worldly and next-worldly success, out of genuine concern, and ask Allah that He clear her heart of such bad thoughts.
And Allah alone gives success.
