Mustadrak al-Hakim — Hadith 8343

It is narrated from Mansur, from Ata and Mujahid, and they narrate from Ayman (they said that Ayman was a man who was spoken of with good) that he said: The hand of the thief is not cut off for less than the value of a shield, and at that time the value of a shield was one dinar. So Ayman the son of Umm Ayman, who is a Companion and the maternal brother of Usamah, is far too eminent and illustrious to be attributed to obscurity by saying of him, "He was a man who was spoken of with good"; such a statement is only made about an unknown person (majhul) whose companionship of the Messenger is not known. Moreover, Jarir has kept this narration mawquf at this Ayman and did not make it marfu' (with a connected chain to the Prophet).
