I don't believe in any religion, but I have researched this issue before.

There are verses in Islam that directly prohibit gambling. In Christianity, there are no such verses, but criticisms such as unjust gain and waste are associated with gambling. In Judaism, gambling is seen as a useless habit.

Religions have prohibited gambling to protect the peace of society and the moral law.

People who gamble sometimes disagree and clash with each other. I think the purpose of religion is to prevent situations like this. Also, gambling causes addictions. Gambling addiction can lead to psychological and physical problems. Also, I have seen people who gambled away their family's food money. Also, I have seen some people who gamble lose their families.

Religions have created some solutions for people who had problems in the past. I don't think we need them, but there are still people who need them. Religions are cultural heritages that provide solutions for social problems.
