What is the ruling on saying: "O Hijaz, gently, for within you is a person worth all of humanity; beware lest your atmosphere troubles his chest," and "O sky of the Eastern Province, please rain down and wash away the heart of every distressed person and heal every sick person, O Lord"?

These phrases are metaphorical. The saying: "O Hijaz, gently" and "O sky of the Eastern Province, please rain" is an example of metaphorical attribution to the cause, time, or place of an action. There are many such examples in the Arabic language, and the Prophet, peace be upon him, used similar expressions, such as his saying: "Paradise is under the shade of swords." As for the phrase "worth all these people," it contains hyperbole.
