Each of these two methods has its own specificities. The Mutakallimoon established the Qawaa’id (principles) stripped from the branches whilst the Fuqahaa established the Qawaa’id guided by and derived from the branches. Both methods or approaches have their own merits and specificities that are not found in the other.

Some of the writers in Usool ul-Fiqh combined both methods in the case where they took what each was distinguished by in terms of its merits whilst casting aside and leaving that which criticism had been directed towards.
