Abstinence does not prevent the existence of a child, and the decree of Allah is executed

Question:
So what is the comparison of resolve to a vow?

Answer:
Then he said: "There is no matter that is not going to happen; there is no matter that Allah has foreknown in His knowledge to happen but it will happen." Then the Prophet (peace and blessings be upon him) said that resolve does not prevent the existence of a child in my beloved. And even if it is not like [a vow]. Resolve has a type of causation, but it does not prevent [the outcome]. Yes.
