More than 50% of the world population gamble in one sport or the other and some are making good money while some are still hoping and praying for their luck to shine.
No, gambling can never be a source of income. If a person thinks gambling is the only source of income, then I would say his mentality has problems. However, more than 50 percent of the world's world can consider gambling and gambling as a source. However, even if many can make good money, everything can be seen once in calculation. Losing money is much higher than that. That is why you should find alternative roads, not to make money by gambling. Then it will be easy to make money in a halal way instead of losing a person and will be happy.
It will not have any problems.
