Explanation:

- Order 5, Rule 30: This talks about the procedure for serving the summons to the defendant and not about stating relief in a plaint.

- Order 9, Rule 12: Deals with setting aside the dismissal of a suit, not relevant to the relief claimed.

- Order 7, Rule 7: This rule requires that every plaint must specifically state the relief claimed by the plaintiff. This makes it clear what outcome the plaintiff seeks from the court.

- Order 10, Rule 22: Not related to stating relief, it refers to the examination of parties at the first hearing.
