'Abdullah bin Mas'ud, may Allah be pleased with him, narrated that the Messenger of Allah (may the peace and blessings of Allah be upon him) said:" Have Haya' (modesty) for Allah as is due to him." [He said:] We said: "O Prophet of Allah! We have Haya', and all praise is due to Allah." He said: "Not that, but having the Haya' (modesty) for Allah which is due to him is to protect the head and what it contains and to protect the abdomen and what it includes, and to remember death and the worn body, and whoever seeks the Hereafter, shall leave the adornments of the world. So whoever does that, then he has indeed fulfilled Haya', which is due to Allah."
