Oath regarding a future event that was expected to occur but did not

Question:
Honorable Shaykh, may Allah grant you success. If a person swears an oath that a future event will occur, but it does not occur, does he have to pay an expiation? Yes. If a person swears an oath that a future event will occur, but it does not occur, does he have to pay an expiation?

Answer:
If he intends that he himself will do it, meaning he will do it but does not, then he has to pay an expiation. But if he intends that it will happen by the decree of Allah, then this is not a valid oath, because he does not have control over that matter; rather, it is up to Allah. If he swears, "It will surely rain tomorrow" or "The wind will surely blow tomorrow," and he swears to this, this is not a binding oath; because he swore to something that is not within his action and not under his control. Yes.
