Orderly Unfolding — "He Knows What They Conceal and What They Announce"

Definition of laf and nashr (envelopment and unfolding):
Mentioning multiple items (envelopment) then following them with their rulings or descriptions (unfolding) — either in order (each ruling matches its preceding item in sequence) or scrambled (a ruling does not directly match its counterpart).

The verse — orderly unfolding:
"He knows what they conceal and what they announce." (2:77)

Analysis:
Two matters are enveloped: (1) the secret (2) the announced — then the ruling "He knows" is unfolded upon them — the unfolding is orderly because one ruling covers both together.

A more detailed example:
"And of His mercy He made for you the night and the day — that you may rest in it and seek of His bounty." (28:73)
Enveloped: night and day. Orderly unfolding: "that you may rest" matches night, "seek of His bounty" matches day.

Rhetorical effect:
Concision with comprehensiveness — elements are mentioned together then the ruling is distributed over them — more impactful than detailing them in two separate sentences.
