سُلُوكُ سَبِيلِ التَّرَقِّي
Proceeding from a general description to a more particular and elevated one.
هَذَا الْكَلَامُ صَحِيحٌ فَصِيحٌ بَلِيغٌ
This speech is correct, fluent, and rhetorically effective.
Sahih indicates correctness. Fasih adds ease and acceptability of expression. Baligh additionally indicates effective conformity to the occasion. The audience passes gradually to more demanding qualities.
The order thus expresses progression from general to particular or from a basic description to a more comprehensive excellence; the sequence is not just a decorative enumeration.
