If one prays and did not wipe his ears during the ablution, does he repeat the ablution and the prayer?

The questioner:
Yes. Honorable Shaykh, may Allah grant you success, a man performed the ablution and did not wipe his ears, believing that it is not among the obligatory acts of the ablution, then he prayed. Is his prayer valid?

The Shaykh:
The matter is easy for him. He performs the ablution again and prays anew, because wiping the ears, both the outer and inner parts, is obligatory, as they are part of the head. Just as he is required to wipe his head, he is required to wipe his ears. Yes, otherwise he would not have completed wiping his head. Yes.
