Are you a Christian? A muslim? If not, I don't think it is a sinful thing. Or is gambling in your country? If still no, why are you sinful? It is real life.
I think that gambling is really a part of our life. I am not referring to gambling games but in our daily life. We people really encounter problems in which we should have to gamble
It's very wrong, if you said it then you are already entered into the black ring (addiction), gambling. Because the majority of people in this world do not use the gambling, but they still can live very well and can also get something they want in a short time. So it's not about gambling, but into a matter of thought. If we are wrong to think and not be able to see all sides it will be bad
