If one performs wudu' and sees a white spot that he did not wash on his elbows after wiping his head, does he have to repeat the wudu' from the beginning?

Question:
May Allah reward you, Your Eminence, father. The questioner says: If the one performing wudu' sees a white spot that he did not wash on his elbows after wiping his head and ears, does he wash this white spot and then wipe his head and ears, or does he repeat the wudu' from the beginning?

Answer:
He repeats what comes after it, while what comes before it is valid. He repeats the limbs that come after it, while what comes before it is valid, and the order is not disrupted by this. Yes.
