سَائِلُ اللَّئِيمِ يَرْجِعُ وَدَمْعُهُ سَائِلٌ
The petitioner returns from a miser, his tears flowing.
The first sāʾil introduces a person who comes in need; the second describes tears in motion. Repetition of the same form accompanies a shift of meaning, while the concluding word returns the listener to the opening picture of frustrated need.
This shows why a verbal ornament may intensify meaning rather than merely decorate sound. The miser's stinginess and the petitioner's disappointment become more forceful through the exact arrangement of the repeated form.
