The Deep Faith of Muslims

Salam alaikum! So, I’m a Buddhist and honestly, I don’t know much about Islam or how you all practice your faith. But one thing I’ve noticed is how Muslims seem to dedicate their whole lives to living by their holy book. I’ve never seen that kind of commitment in any other religion. What I’m curious about is, why do you actually live that way? How do you get to that level of devotion as a person? Is it something passed down in families, or are there real consequences if you don’t follow the teachings? Like, imagine you had to miss Jumu’ah prayer at the masjid for a genuine reason, just once. Would you feel guilty about it? Are the effects just inside your heart, or do you face actual problems in life if you’re not following the path?
