Musannaf Ibn Abi Shayba 33:772

Ibn Idris narrated to us, from Layth, from Abu al-Zubayr, from Ubayd ibn Umayr, regarding His saying: "A cruel person (atall), and moreover, illegitimate (zanīm)." He said: He is the one who eats much, drinks much, and is harsh/strong, yet if he were to be weighed, he would not weigh as much as a barleycorn. The angel will push seventy thousand of those [people] into Hell at one time.
