What is the ruling on using the "Lucky Day" application to earn money by participating in lotteries and scratching cards using the application's points?

Participation in a lottery, whether with money or with points that have monetary value, is impermissible because it is a form of forbidden gambling (qimār and maysir (definition)). This is based on the Almighty’s saying: "O you who have believed, indeed, intoxicants, gambling, [sacrificing on] stone altars [to other than Allah ], and divining arrows are but defilement from the work of Satan, so avoid it that you may be successful." It is not permissible to use an application if it is exclusively designed for this purpose. However, if it serves multiple purposes and is available for permissible uses, then there is no objection.
