Ibn 'Abbas (May Allah be pleased with them) said:
The Messenger of Allah (ﷺ) saw an ass which had been branded on the face. He disapproved of it. Upon this Ibn 'Abbas (May Allah be pleased with them) said, "By Allah, I shall not brand (the animal) but on a part at a distance from the face." Ibn 'Abbas (May Allah be pleased with them) then commanded branding on the hips; he was the first person to brand the animals on hips.[Muslim].
