Anas ibn Malik said, "A man came to the Prophet, may Allah bless
him and grant him peace, to ask him for a mount. He said, 'I will give
you a she-camel's foal to ride.' He exclaimed, 'Messenger of Allah, what
can I do with a she-camel's foal?' The Messenger of Allah, may Allah bless
him and grant him peace, said, 'Are camels born from anything other than
she-camels?'"
