Narrated Anas: I brought a brother of mine to the Prophet to do Tahnik for him while the Prophet was in a sheep fold of his, and I saw him branding a sheep. (The sub-narrator said: I think Anas said, branding it on the ear.)

Narrated Anas bin Malik: I took `Abdullah bin Abu Talha to Allah's Apostle to perform Tahnik for him. (Tahnik was a custom among the Muslims that whenever a child was born they used to take it to the Prophet who would chew a piece of date and put a part of its juice in the child's mouth). I saw the Prophet and he had an instrument for branding in his hands and was branding the camels of Zakat.
