Suppose an elder brother gives advice on a family matter. A younger brother listens respectfully but may explain a different view with evidence and courtesy. Respect need not eliminate thoughtful discussion.
If an elder asks a younger sibling to be unfair, giving in is not the only way to show respect. Genuine goodwill requires avoiding wrongdoing and explaining the issue appropriately.
The pattern حَقُّ ... عَلَى expresses one person's right in relation to another. It reminds us that rights and responsibilities go together.
