Inshaallah

The real meaning is abused and manipulated.

So yes, you can say that if someone says it, maybe... it means they are not going to do whatever it is they are promising, and they hide behind this word for not taking responsible at all.

Actually the real meaning is "God willing" or "I will do my best but Allah will is what will decide what will happen" but some people say it and mean "God will not want it to happen".

So in which group are you?
