Have you ever prayed before placing a bet (gambling)?
Did it work?
I pray a lot and I'm also praying when placing a bet or rolling a dice, it doesn't matter if I win or not the most important is I am putting faith in my belief and the almighty, you can pray in any situation any place and any condition, it's beneficial in both body and mind and I don't see anything wrong why you should pray when gambling.
Yes, indeed. There will be up to you or people whether they want to pray to God and ask for help to win the games or never pray to God when they are gambling. If they believe that can help them and give them confidence, they can still pray without listening to what other people say. When we play gambling, we are free to do what we want, as long as we do not break the rule in the casino.
