Musannaf Ibn Abi Shayba 11:62

Waki’ narrated to us, from Mis’ar, from Muhammad ibn ‘Abd al-Rahman, the freed slave of the family of Talhah, from ‘Isa ibn Talhah, from Abu Hurayrah, who said: The dust of the path of Allah and the smoke of Hell shall never gather in the nostrils of a servant, ever. And a man who wept out of fear of Allah shall never enter the Fire, until the milk returns into the udder.
