Sunna vs. Mandub

Q
As-salam aleykum,
Dear brother,

Three of the four madhhabs classify sunna ccording to different
levels. they name Mandub, sunna, raghiba, fadhila and nafila. I have
read somwhere that the Hanbali school considers only one level for
sunnas. Is that true or perhaps it is only valid for Mandoub and Sunna?

Some scholars (out time's Sh. Al-ghazali from Egypt who was Hanbali ,
i think) may Allah have mercy on him clasifies sunna into two types.
Sunna of `ada (habitude) and sunna of `ibada. Please could you
elaborate on these issues with all the opinions on the 'market' it's
har to see the light.

Sheikh `Abd al-Qadir ibn Badran wrote in his introduction to Akhsar al-Mukhtasarat that "Mandub is [also] called: sunnah, mustahabb (recommended), tatawwa` (voluntary), ta`ah (obedience), nafl (supererogatory), qurbah (devotional), muraghghib fihi (encouraged to do), ihsan (perfection)." The basic explanation for why these are the same is that something that is sunnah is also mustahabb, and something that is mustahabb is also tatawwa', and so on.
 
Classifying the actions of the Prophet (Allah bless him and give him peace) into habitual and otherwise typically falls under the subject of usul al-fiqh-- where the concern is legal significance --not fiqh. These terms in and of themselves are nothing new, although some scholars may apply them in novel ways.

What I wrote applies to the Hanbali and Shafi`i madhhabs. For the Hanafis and Malikis it is best to ask someone who has studied their usul from scholars of those schools.

And Allah knows best.
