Vitabu vya Mustalah vinazungumzia madaraja kadhaa ya hadithi kulingana na hadhi zake. Mgawanyo mpana ufuatao unaweza kufanywa, ambapo kila moja inaelezwa katika sehemu zinazofuata.

Mustalah books speak of a number of classes of hadith in accordance with their status. The following broad classifications can be made, each of which is explained in the later sections:

Kulingana na kumbukumbu ya mamlaka fulani, kwa mfano Mtume (rehema na amani za Allah zimshukie), Sahaba, au Tabi'i; hadithi kama hizo huitwa marfu' (iliyoinuliwa), mauquf (iliyosimamishwa) na maqtu' (iliyokatika) kwa mpangilio huo.

• According to the reference to a particular authority, e.g. the Prophet (may Allah bless him and grant him peace), a Companion, or a Successor; such ahadith are called marfu' (elevated), mauquf (stopped) and maqtu' (severed) respectively.

• Kulingana na viungo vilivyomo katika isnad, yaani kama mlolongo wa wapokezi umekatika au haukukatika, mfano musnad (ulioungwa), muttasil (endelevu), munqati' (uliokatika), mu'allaq (unaoning'inia), mu'dal (wenye kutatanisha) na mursal (wa haraka).
