Sulayman bin Abi Abdullah said: I saw Sa'd bin Abi Waqqas (may Allah be pleased with him) seize a man who was hunting in the sanctuary of Madinah, which the Messenger of Allah (peace and blessings be upon him) had made sacred, and he stripped him of his clothes. His masters came and spoke to him about it, and Sa'd bin Abi Waqqas (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) made this sanctuary sacred and said: "Whoever catches anyone hunting in it, let him strip him of his belongings." So I will not return to you a provision that the Messenger of Allah (peace and blessings be upon him) granted me; but if you wish, I will pay you its value.
