I'd say it is quite familiar to Christianity. Canon Law mirrors the secular legal system, complete with its own lawyers, courts and so on. (Arguably, it's the other way around: secular Western law that mirrors Canon Law.)

Only the most extremist of Muslims, the Salafi, take the Jewish legalistic idea, majority of other traditions in Islam lean towards Tafsir that squarely leans on “spirit of the law” than strictly the word.
>the Salafi, take the Jewish legalistic idea
What is "the Jewish legalistic idea"? It's not a monolith. What makes a salafi a salafi has nothing to do with legalistic ideas.
>majority of other traditions in Islam lean towards Tafsir
This also doesn't make sense to me, as tafsir is exegesis of Quran. Salafis and all muslims care about tafsir.
The core differences between different groups of muslims, loosely in order of priority, is which sources to take from after the demise of Prophet Mohammed, and then how to interpret any sources (incl. Quran) (literally (salafis), logically (shia), etc.).
There are different tafsirs of Quran as well, and can have very stark differences. However loopholes are completely disallowed by all muslims.
For Christians and those raised in the Christian tradition, this is entirely foreign. The rules are not set out nearly as strictly for you, you have to interpret them much more broadly.
Generally, if you read their respective books, the old testament has a set of rules mixed in with a quasi-historical context, while the new testament is almost entirely in the form of parables.
Islam, by the way, goes back toward the Jewish legalistic idea.
