Musnad Ahmad 30:3394

Yazid narrated to us, Muhammad informed us, from Abu Salamah, from Abu Hurairah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The best of the women who ride camels are the women of Quraysh: the most affectionate to an orphan in his childhood, and the most protective of a husband regarding his wealth."
