Musnad Ahmad 30:2552

Abu Dawud al-Hafari narrated to us, from Sharik, from Suhayl ibn Abi Salih, from his father, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Two types of my nation are among the people of the Fire, whom I have not yet seen: women who are clothed yet naked, inclining and causing others to incline, upon their heads are like the humps of camels; they will not enter Paradise, nor will they find its fragrance. And men who have with them whips like the tails of cattle, with which they strike the people."
