So can you tell me why is it forbidden in your religion?
And for the non religious persons what you think ?
The title is wrong all religions forbid gambling not only some, but all the popular religions forbid gambling, Muslims, and Christians are forbidden to gamble Buddhism forbids gambling because it's bad for karma, I don't think there is a popular religion that will encourage members to gamble its for the pocket bad for the family and bad for the health of the members.
I will leave my religion if its doctrine allows its members to gamble, they will lose their followers and the respect of their followers, my religion forbids its followers to gamble it's my own choice to gamble and I will not feel guilty as long as I do not exceed my limitation and only gamble for fun.
