«يا خاطبَ الدنيا الدنيّةِ إنها شَرَكُ الرَّدى وقَرارةُ الأكدار»
Seeker of this lowly world, it is a snare of destruction and a dwelling of sorrows.
The earlier ending «الرَّدى» and the later ending «الأكدار» provide two possible rhyming closures. At the first point, the claim that the world is a snare of ruin is complete. The later phrase expands the judgment by adding a dwelling of sorrows.
The skill is the availability of two meaningful closures, not synonymy between the ending words. The second ending extends an already coherent statement.
