This is a very common tree in Oman.
Catalogue of Life lists three varieties. Out of which Ziziphus spina-christi var. aucheri (Boiss.) M.Qaiser & S.Nazimuddin is reported from Pakistan.
Pl. confirm.

..., leaves are totally glabrous, so it should be type variety only
In your 1st images, I see 'Leaves pubescent or at least pubescent at nerves beneath'

Yes … you are right.
Was it a cultivated one ?
Don't remember now, roadsides in a small town
