Narrated Anas ibn Malik:
A man came to the Prophet (peace_be_upon_him) and said: Apostle of Allah! give me a mount. The Prophet (peace_be_upon_him) 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 (peace_be_upon_him) replied: Do any others than she-camels give birth to camels?
