It is He who blocks the way (of guidance, health or elevation) and it is He who leads the way to it.
Verily You elevate whomso You wish and You abase whomso You wish.
(26, Al-Imran).
Note: Once Shah Abdul Latif, while in ecstasy, blessed a blind man and the latter regained his eye sight. When the poet returned to normalcy, he denied all contribution to his regaining the sight, but he cited the above verse.

He alone blocks the way, He alone directs,
He elevates whom He pleases, He degrades whom He wishes.

He alone blocks the way, He alone directs,
He elevates whom He pleases, He degrades whom he wishes.

He is the one who leads astray and a perfect guide too,
"You elevate whom so you wish and you abase whom so you wish"*
