The Mudabbar
Malik :: Book 41 : Hadith 41.11.33
Yahya related to me from Malik from Ibn Shihab from as-Sa'ib ibn Yazid that Abdullah ibn Amr ibn al-Hadrami brought a slave of his to Umar ibn al-Khattab and said to him, "Cut off the hand of this slave of mine. He has stolen." Umar said to him, "What did he steal?" He said, "He stole a mirror belonging to my wife. Its value was sixty dirhams." Umar said, "Let him go. His hand is not to be cut off. He is your servant who has stolen your belongings."
