Section : What Obliges Cutting Off the Hand.

Yahya related to me from Malik from Abdullah ibn Abd ar-Rahman abu Husayn al-Makki that the Messenger of Allah, may Allah bless him and grant him peace, said, "The hand is not cut off for fruit hanging on the tree and for sheep kept in the mountains. So when they are taken from the fold or the place where the fruit is dried, a hand is cut off for whatever reaches the price of a shield."
