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.

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: When Um Sulaim gave birth to a child. she said to me, "O Anas! Watch this boy carefully and do not give him anything to eat or drink until you have taken him to the Prophet tomorrow morning for the Tahnik." So the next morning I took the child to the Prophet who was sitting in a garden and was wearing a Huraithiya Khamisa and was branding the she-camel on which he had come during the Conquest of Mecca.
