You can only play at physical casinos that are licensed in your country, and actually they are only for non-Muslims. Casino companies are more compliant with government regulations than religious laws, so they will continue to operate even in a Muslim-majority country as long as your government grants the license.
If I were him, I would try to play at physical casinos instead of online casinos because I think that will be safe for me and I do not break the rule of my government. Besides that, the legality of the casino will not be doubted as the government allow the physical casinos can running without a problem. Maybe later, if my government allow the online casinos to operate from my country or my people can play gambling on the online casinos, I will also play gambling in the online casinos. But do not force ourselves to gamble if the situation is not allowed.
We are still in a pandemic and it's not yet recommended to play in the casinos in fact governments encourage people and companies to transfer their activities online if it's possible and that includes playing in casinos and besides it's convenient to play online at the comfort of your home, going back to the topic the only way to now this is to ask their support or you can email them or message them directly if they have an account here or on their active social media sites.
