If we want to find out about the four madhhabs why should we rely on Hanafis' fatwas?

According to Hanafis:

According to the Mazhab of Imam Malik (A.R.), it states that these socks, (cotton or cloth) must be made with leather inside and outside so that it resembles the leather socks (Khufain)
According to Malikis:

The first precondition is that the sock must either be entirely (top and bottom) made of leather which is pure (and not impure (e.g., the skin of a pig)). This means that the external surface of sock must be leather. Thus, leather sewn on top of cotton/nylon/etc. socks fulfills the precondition, but plain cotton/nylon/plastic/vinyl/etc. socks without leather sewn on top of them do not. Top tip:

Don't always rely on fatwas where they quote four madhhabs as they often have errors
