Musnad Ahmad 30:1544

Aswad ibn Amir narrated to us, Sharik narrated to us, 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 the people of the Fire I have not seen yet: women who are clothed yet naked, deviating and causing others to deviate, upon their heads are like the humps of camels, leaning. 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."
