Musnad Ahmad 1017:48

Yazid narrated to us, al-Mas'udi narrated to us, from 'Alqamah ibn Marthad, from Ibn Buraydah, from his father, who said: A man came to the Prophet, may Allah bless him and grant him peace, and said: "O Messenger of Allah, I love horses, so are there horses in Paradise?" He said: "If Allah admits you into Paradise, then you will not wish to ride a horse of red jacinth that flies with you wherever you wish in Paradise, except that you will ride it." Then another man came to him and said: "O Messenger of Allah, are there camels in Paradise?" He said: "O servant of Allah, if Allah admits you into Paradise, you will have therein whatever your soul desires and whatever delights your eye."
