Musannaf Ibn Abi Shayba 33:1323

Abu Usama narrated to us, he said: Jarir narrated to us, he said: Abdullah bin Ubayd bin Umayr narrated to me, he said: Ayyub (Job), the Prophet of Allah, peace be upon him, had two brothers. They came, but they could not draw near to him because of his odor. One of them said to the other: "If Allah had known any good in Ayyub, He would not have brought him to this state." Ayyub was distressed by their statement with a severe distress, such as he had never felt from anything before. So Ayyub said: "O Allah, if You know that I have never spent a night full while knowing the place of a hungry person, then verify me." So he was verified, and they were listening. Then he said: "O Allah, if You know that I have never worn a shirt while knowing the place of a naked person, then verify me." So he was verified, and they were listening. Then he fell prostrate and said: "O Allah, I will not raise my head until You remove this from me." He said: So he did not raise his head until Allah removed it from him.
