Filthy language is used by people who don't have the maturity or intelligence to express themselves with better words.

The hypocrite takes good advice as an insult.

You can't just pretend that the things you watch, and the things you hear, and the places you go will not have an impact on your character. They will.

Self restraint in speech, food, entertainment and vanity are the most essential fundamental of spiritual growth.

Forgiving someone isn't just about doing good to another. It's also about healing a scar in your own heart.

Islam didn't make it Haram for you to fall in love. It didn't forbid you from wanting someone. It only guides that love so it protects you, her, your families and especially saves you from humiliation on judgment day. If you love her so much, why are you ok with letting her engage in this questionable relationship knowing full well that she will have to answer Allah just like you will. You don't love her enough to save her from that?

Allah will intervene into our emotional states. He can give you tranquillity again; whether it's anxiety, fear, grief, anger - whatever emotion, whatever thing that's happened that has left you scared, Allah can remove that scar entirely.
