Kowace daga cikin waɗannan hanyoyi biyu tana da nata keɓantattun siffofi. Mutakallimoon sun kafa Qawaa'id (ƙa'idoji) da aka cire su daga rassa, yayin da Fuqahaa suka kafa Qawaa'id waɗanda rassa ke jagoranta kuma daga gare su ake samo su. Dukkan hanyoyi ko tsare-tsare biyu suna da nasu fa'idoji da keɓantattun siffofi waɗanda ba a samun su a ɗayan.

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.

Wasu daga cikin marubuta a fannin Usul al-Fiqh sun haɗa hanyoyin biyu a yanayin da suka ɗauki abin da kowace hanya ta fi shahara da shi ta fuskar kyawawan halayenta, suka kuma watsar da barin abin da aka soki.

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.
