The ruling on one who forgets to wipe his head during ablution

Question:
May Allah reward you with good, and may He do you good. After this, a message reached the program from one of the female listeners, who identified herself with the letters Ameen. She asks and says: From the obligations of the Prophet (peace and blessings be upon him), tell us if a person forgets that...

Answer:
...if a person forgets it, his ablution may be incomplete. If he forgets to wipe his head, his ablution is not valid. If he remembers it shortly after, he wipes his head and then washes his feet, because washing the feet is not valid except after washing the head. However, if he does not remember it until the time has passed and the continuity has been broken, he must repeat the ablution from the beginning. The point is that if he remembers that he did not wipe his head, and a long time has not passed, he wipes his head and repeats washing his feet for the sake of order, because the continuity remains. But if he does not remember it until the continuity is broken and a long time has passed, he repeats the ablution from the beginning. Yes.
