How did coffee become a substitute for alcohol in parts of the Muslim world?

In the Muslim world, coffee became a popular beverage largely due to its stimulating effects, which attracted many people to it as a substitute for alcohol, a substance prohibited by the Qur'an.12

Although some Islamic authorities ironically argued that the drink was intoxicating and should also be banned under religious law, its consumption spread rapidly among Arabs and their neighbors. This popularity led to the rise of the coffeehouse, or qahveh khaneh, which became a significant social and cultural institution. Despite occasional attempts by religious and political leaders to prohibit these establishments due to fears regarding the free discourse that took place within them, the drink had become so deeply ingrained in daily ritual and culture that such bans proved impossible to maintain.12
