وَفَوْقَ كُلِّ ذِي عِلْمٍ عَلِيمٌ
And above every possessor of knowledge is one who knows more.
Quran example — Surah Yusuf 12:76
- فَوْقَ identifies the relation of being above, so it is the adverb of place.
- It is mudaf and therefore has no tanwin.
- كُلِّ ذِي عِلْمٍ completes the relation: above whom?
The target here is the clear idafah فَوْقَ كُلِّ.
