I have a friend who enjoys gambling. What is the Islamic opinion that can convince him stopping the evil game?

Question

Islam prohibits games, which involves betting or an element of gambling in it. It is not lawful to seek relaxation and recreation in gambling. The Islamic teachings urges the Muslim to follow Allah’s directive for earning a living, to use natural laws and direct means for the attainment of his/her objectives, and employ such causes to produce the desired effects. Gambling makes a person dependent on chance, and empty wishes, taking him away from honest labour, serious work and productive effort. In Islam, an individual’s property is sacred; it may not be taken from him except through lawful exchange or unless he gives it freely as a gift or charity.
