The problem is that we have to ‘show’ not ‘tell’ our children and the accountability reaches to what they learn from us as well. You have the intention, mashallah, so Allah (swt) will help you overcome this ingrained habit. Either quit ‘cold turkey’ or place a ‘patch’ on it when you feel your temper flaring.
Your children will admire you for making the effort and they will apply it to their lives as they have to struggle with unhealthy habits of their own.

‘Haya’ in Islam definitely refers to ‘modesty’ in speech as well.

Like smoking, this is something that is very hard to stop when it’s been ingrained in you for years. I’m embarrassed to say that even though I’ve been Muslim for many years, bad words still come out when I’m very angry. I know that it’s a choice I make, and I’ll be held accountable, but they come out before I even have time to think. So as I tell my children, don’t ever start this habit!

I think this kind of danger also gives broader perspective to the Islamic etiquette of ‘lowering the gaze’. It’s not just looking at the opposite sex that can lead down the wrong path, but it’s seeing ANYthing potentially harmful – and unfortunately, we’re exposed to it in even the most public of places.

Lowering the gaze and minding your own business is a somewhat effective way to protect against those dangers.

Ameen.

I personally don’t think it is appropriate to use those either. The mind automatically substitutes the profanity for the seemingly harmless word and the effect is the same. The intention is also the same:to say something startling and unconventional and get some attention.
