Ushbu ikki usulning har birining o‘ziga xos xususiyatlari bor. Mutakallimun qoidalarni (asoslarni) tarmoqlardan xoli holda belgilagan, fuqaho esa qoidalarni tarmoqlarga suyangan holda va ulardan kelib chiqqan holda belgilagan. Ikkala usul ham bir-birida topilmaydigan o‘ziga xos afzalliklar va xususiyatlarga ega.

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.

Usul al-fiqh ilmidagi ba'zi olimlar ikkala usulni birlashtirib, har birining o'ziga xos afzal jihatlarini olib, tanqidga uchragan qismlarini esa tark etgan holda ish tutganlar.

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.
