Abbas was traveling alongside the Prophet ﷺ on a camel that had been branded on its face with fire.The Prophet ﷺ asked, "What is this brand, Abbas?"Abbas replied, "It is a brand we used to mark our camels with in the days of ignorance."He said, "Do not brand with fire."
كان العباس يسير مع النبي ﷺ على بعير قد وسمه في وجهه بالنار، فقال: ما هذا الميسم يا عباس؟ قال: ميسم كنا نسمه في الجاهلية فقال: لا تسموا بالحريق.

Tabarani (11/350) narrated it from Zakariya bin Yahya Saji, from Muhammad bin Muthanna, from Uthman bin Umar, from Uthman bin Murrah, from Ikrima, from Ibn Abbas, and he mentioned it.Its chain of transmission is hasan because of Uthman bin Murrah, for there is no harm in him.
