The arrangement of sūrahs and verses should not be reduced to ordinary textbook chapters or the metrical patterns of classical poetry. Qur’anic discourse combines varied openings and endings, shifts of subject, sonic correspondence at verse endings, and variable verse length.
Verse versus poetry: Qur’anic passages may display rhythm and acoustic beauty without being bound by the traditional metres of verse. Some passages have short endings while others sustain longer clauses; the form serves the rhetorical and interpretive purpose.
If neighboring verse endings sound alike, do not make rhyme the sole determinant of meaning. Start with grammar, the subject, and the relationship at the pause; then recognize sonic pattern as an additional, related dimension.
