Musannaf Ibn Abi Shaybah 38093 — Reports from Abu Ubaydah

Abu Ubaydah said: An arrogant and rebellious man said: "I will not stop until I see who is in the heaven." Thereupon Allah Almighty set over him the weakest of His creatures. A gnat entered his nose and became the cause of his death. He would say: "Strike my head," and people struck his head until they scattered his brain.
