Ibn 'Abbas (May Allah be pleased with them) said

An ass with a brand on the face happened to pass before the Prophet (ﷺ). Thereupon he said, "May Allah curse the one who has branded it (on the face)."

[Muslim].

Another narration in Muslim is: "The Messenger of Allah (ﷺ) prohibited us from hitting across the face and branding on the face (of an animal)."
