One verse may contain two or three recognizable internal units distinguished by sense and cadence. Though long on the page, the verse may unfold through smaller organized phrases that guide the listener step by step.
“Yawma tabyaḍḍu wujūhun wa-taswaddu wujūh”
“On the Day when some faces will become white and some faces will become black.” (Āl ʿImrān 3:106, excerpt)
The verse continues by distinguishing the groups in greater detail. Its initial contrast prepares the later explanation, so internal balance must be understood as part of the meaning of the whole verse. An internal clause boundary is not identical with the end of a verse.
