In Indonesia, as a country that is mostly Muslim. Every adherent of Islam is ordered to follow the Islamic Sharia in finding income, namely by means and a good way. Gambling will make someone only rely on good luck, coincidence and empty dreams. Therefore, gamblers do not want to work hard to get good and halal income.
The position of human property in Islam is something honored. It is forbidden to take arbitrary mena, except in a way that has been prescribed in the form of voluntary giving. Gambling is an act of betting some money or something that is considered valuable. People who win get their money bets, in other words fighting or profit. Gambling is an activity with unexpected results before and the law is prohibited in Islam. God forbids His faith servants to do the act of drinking alcohol and gambling drinks. This is contained in the Qur'an Surah Al Maidah verse 90 which reads "O people who believe, actually drink kahmr (alcohol), gambling, idols, drawing fate with arrows is a heinous acts including demon. so you get luck "
In the verse it is stated that the behavior of gambling and drinking alcohol is a demonic deed. This means that such activities must be avoided. If you do that, you will not get a blessing from God and kept away from luck.
In Islam, gambling is a disgusting act, gambling can cause quarrels and hostility, gambling also reduces the enthusiasm of work because of getting money instantly.
Because humans are given the ability by God to take the way to work and slam bone so that they can get some of the pleasure of the world and the comfort of life. Whereas gambling is not an effort that brings income by way of work relationships but the nature of guessing suspects, even fantasizing that is not clear. People who do gambling are in two opportunities, namely winning or losing. If he wins he will be more arrogant in obtaining his wealth, whereas if you lose he will return in gambling with the aim of withdrawing the money that has been lost. So with that it continues to happen, people will be busy doing gambling and can even leave their obligations to work. If the gambler is a rich man, while he accepts his defeat he will have the opportunity to fall, turn poor or the condition in which he is frustrated and loses his mind. Not infrequently also from gambling perpetrators are people who have jobs and used to get money/salaries they get. If he already has a family, he has the obligation to provide a halal living to meet the needs of his family. If the wages during his work are used for gambling, then his family will be threatened with being abandoned because it is not fulfilled. Because someone who has been addicted to gambling, he will continue to try to have enough funds to gamble. It could be that he can justify any means to gamble. Therefore, accumulate behavior that violates Islamic Sharia.
What I said above is a variety of wisdom and reasons that can be understood from why gambling is forbidden in Islam.
Hopefully my explanation can be understood by all friends
