The same root ẓ-l-m produces two different perspectives in verse 38:
يُظْلَمْ — passive imperfect: he is wronged.
يَظْلِمْ — active imperfect: he commits wrong.
Changing the grammatical voice also changes moral agency. Someone initially presented as a victim of injury may become the initiator of injury. This is more than a formal change of verb pattern.
