Amrah bint Abd al-Rahman said that she heard Aishah (may Allah be pleased with her) say that the Messenger of Allah (peace and blessings be upon him) said: "The hand is not to be cut off for a theft of less than the price of a shield." Aishah (may Allah be pleased with her) was asked: What is its price? She said: A quarter of a dinar.
