«وَالظُّلْمُ مِنْ شِيَمِ النُّفُوسِ»
Injustice is among the habitual tendencies of souls.
The poetic example gives metrical form to an ethical observation about human nature. In ‘aqd, material that could be stated as prose is shaped into verse.
The conversion fails if meter forces the writer to drop an essential qualification or distort the point. Good ‘aqd preserves the insight while giving it a coherent and effective poetic form.
