Its a fact that the hadith are clear,and about your question i can only say this.Its an established fact that 2 +2 = 4 but for a child to know it it requires a teacher.
So did Islam our mind is not mature enough to understand truly in a sense what God said. So Muhammad PBUH explained that to us as a teacher.

and as for opinions thing Muhammad PBUH said many if any question rises after He is gone . Muslims would be able to solve ot properly if they sit down together.This is called Qiyas and u can see it. eg there wasn't body transplants in that era so by establish facts from the quran. they create another fact. rg

Alchahol is haram cause it cause intoxication so all the other things which cause intoxications are also haram.

So it is encouraged in Islam by the prophet that if answer is not found in hadith u can find it indirectly in the Quran just do qiyas like the eg i gave u thanks.
