Expiation for Divorce

A man who smokes said to his wife: You are divorced if I smoke.
He left it temporarily, then returned to it, then stopped and repented, and he is now on his repentance?
He owes nothing except the expiation for an oath, which is to feed ten poor people,And that is because his saying to his wife: You are divorced was said only to emphasize his refusal to smoke, and his intention was not to separate from his wife,So, based on this, we say: As long as you intended to emphasize your refusal of it and then returned to it, you owe nothing except the expiation for an oath.
