It is narrated from Sayyiduna Khursha bin Har (may Allah be pleased with him) that I heard the Prophet (peace and blessings of Allah be upon him) say: After me, tribulations will appear. In that time, the one who is asleep will be better than the one who is awake, the one who is sitting will be better than the one who is standing, and the one who is standing will be better than the one who is walking. Whoever faces such a time should take his sword to a stone and strike it until it breaks, and in the face of these tribulations (instead of standing up) should sit down, until the light appears.
