Musannaf Ibn Abi Shayba 3:5634

Muhammad ibn Abi ‘Adi narrated to us, from Yunus, from Humayd ibn Hilal, who said: Hudhayfah was asked about a man who finds moisture after wudu (ablution). He said: "I would not care if it was after the wudu, whether it was that or this," and he gestured with his hand toward his mouth.
