You're just reminding not judging...

Morally corrupt people don't want to hear about their dutty ways. And that's why they hate moral reminders. They will accuse you of making a show of being morally better than them, just because you said "God and Nabi said." But that shouldn't dissuade you from doing your thing.

In fact, the advice you give is a reminder to you, as much as it is to the one being advised, because through it, you're challenging yourself to do better, or to show that you could actually do better.

And that's what's up! We need to be able to do what we say other people should do, otherwise, knowingly or unknowingly, we'll be hypocrites (munafiqs). And that's both a sickness and a crime, ask any Mufti.
