Aqsaam (Categories of) Al-Qiyaas and their level of degree in respect to the Hukm in the view of some of the ‘Ulamaa’
Al-Qiyaas is built or based upon the shared commonality of the Far’u (branch) with the ‘Asl (origin) in respect to one single ‘Illah however the ‘Illah could be stronger (or more evident) in the branch than it is in the origin. This is the Qiyaas Al-Awlaa.
It could also be equal in the branch as it is in the origin. This is called Al-Qiyaas Al-Musaawiy.
And it could be weaker in the branch than it is in the origin. This is called Al-Qiyaas Al-Adnaa.
1 – Al-Qiyaas Al-Awlaa:
This is when the ‘Illah of the branch (Far’u) is stronger than it is in origin (Asl) and so the establishment (or proof/affirmation) of the Hukm in the branch is Awlaa (more evident or applicable) than in respect to the origin.
Example:
Allah Ta’Aalaa says:
So do not say to either of them (parents) (as much) as ‘Uff’ (a word of disdain/displeasure) (Al-Israa’ 23).
The text here prohibits At-Ta’feef (showing displeasure/disdain)
