Musnad Ahmad 30:1992

Abu Ahmad al-Zubayri narrated to us, he said: Sufyan narrated to us, from Abu al-Zinad, from Abd al-Rahman al-A’raj, from Abu Hurayrah, from the Prophet, peace and blessings of Allah be upon him, who said: "The best of the women who ride camels are the women of Quraysh; they are the most affectionate toward a child, and the most protective of a husband’s possessions."
