Sayyiduna Ismah (may Allah be pleased with him) said: A man announced his lost animal in the mosque, so the Messenger of Allah (peace and blessings be upon him) said (to the Companions): "Say: May Allah not return your lost property to you," and he (peace and blessings be upon him) disliked saying these words himself.
