I think it’d be pretty miserable. The religious Muslims I know are extremely paranoid to the point of delusion & very self-hating. Islam is a religion of ethics, with a haram / halal (unlawful / lawful) system which can be applied to quite literally every single micro action in your life. If you were to do it “by the book” it’d limit your life to the point of misery. Even music is considered haram. There are even rules about grooming your pubes / armpit hair. Definitely easier. I was raised fairly secular actually for a Muslim but still taught about Islam and everything.
