I know that this is very silly and religious question but I think that this should be Discussed.
According to me, As I am Muslim, Gambling is Haram and there are very reasons behind this. And also I do not much about another religions. But if someone has knowledge about that if Gambling is allowed or prohibited in Jewish or Christ Faith. And I think many people have many mind sets.
I do not want to hurt someone's feeling by talking about Religious Comments.
Well, according to Islam, gambling disassociates people from Allah's way. For instance, when a gambler is determined to play and the time for prayer comes, he wouldn't want to stand up even when it is time for prayers, which is why it is prohibited. However, I believe that gambling was different in the past compared to how it is now. I'm not trying to modernize Muslims, I just think that their practices were different.
I'm a fan of the sport, it will only take me a few minutes to place my bets with a bookmaker following after analysis. After that, whatever happens, is out of my control, and I don't believe it will have an impact on my salat or prayers. Qatar hosted the World Cup this year despite the fact that they are an Islamic nation, even though they are aware that it will encourage gambling, it should be seen as entertainment rather than a sin.
