Between the Quran and Hadiths, it literally dictates everything that we should do, everything that is a crime, and really holds everything that anyone could ever really need. More Muslims are more religious because Islam is made to not only act as a religion, but also to dictate laws, and how to live. Some of the obvious requirements of Islam are 5 daily prayers, fasting for an entire month, and giving to charity, so just by the start it is a very hands on religion that really requires a lot of work.
While I can see some people not following the rules as strictly as they should, I think that simply believing isn't enough for the faith of Islam. The Quran, how many dozens of times mandates daily prayer? Not being a very religious Muslim, in my opinion from my interpretation of the Scripture, isn't really being Muslim at all. It's essentially a requirement of the religion to be religious.
Compare it to Christianity per say, where their holy book only mandates that they believe in Jesus as the son of God to get to heaven. While there are rules for Christianity for sure, the entire structure is more lax. There are things Christians can't do, but there aren't really things that Christians are mandated to do. I was born and raised Christian (Muslim now), but while I was given restrictions, I never had any requirements dictated to me from the Bible. In the Quran though, it essentially mandates you to be religious. That's the key thing in my opinion. Our Scripture specifically mandates us to do things, which makes us more religious and not "lax" as other religions.
