Sunan Abi Dawud

Narrated Anas ibn Malik: A man came to the Prophet (ﷺ) and said: Messenger of Allah! give me a mount. The Prophet (ﷺ) said: We shall give you a she-camel's child to ride on. He said: What shall I do with a she-camel's child? The Prophet (ﷺ) replied: Do any others than she-camels give birth to camels?
