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].

وعن ابن عباس رضي الله عنهما قال: رأى رسول الله ﷺ حمارًا موسوم الوجه، فأنكر ذلك؟ فقال: والله لا أسمه إلا أقصى شيء من الوجه، وأمر بحماره، فكوي في جاعرتيه، فهو أول من كوى الجاعرتين. ((رواه مسلم)).
