CHILD STEALING. The hand of a thief is not to be cut off for stealing a free-born child, although there be ornaments upon it, because a free person is not property, and the ornaments are only appendages; and also because the thief may plead that he took the child up when it was crying, with a view to appease it, and to deliver it to the nurse. But Abu Yusuf does not agree with Hanifah; for he says where the value of the ornaments amounts to ten dirms, amputation is incurred. Amputation is also inflicted for stealing an infant slave, because a slave is property, though Abu Yusuf says it is not. (Hidiyah, ii. 91.)
