مَعْصِيَتِكَ / نَاصِيَتِكَ — سِيرَتِكَ / سَرِيرَتِكَ
Disobedience / forelock — conduct / inward secret.
حَالُكَ / ارْتِحَالُكَ — مَالُكَ / أَعْمَالُكَ
Condition / departure — wealth / deeds.
Each pair uses corresponding sounds. In this sajʿ, sound reinforces the moral contrast: defiance versus sovereignty, outward conduct versus secrets, present standing versus death, possessions versus deeds.
Rhyming prose here is more than a decorative ending; the ordering of the sounds makes the warning easier to hear and remember.
