Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "A time will come upon the people when a man will call his paternal cousins and close relatives, saying, 'Come towards ease, come towards ease,' whereas if they knew, Madinah would be better for them. By the One in Whose Hand is my soul! Whoever leaves here out of dislike, Allah the Exalted will grant (Madinah) someone better than him. Beware! Madinah is like a furnace, which removes impurities, and the Hour will not be established until Madinah expels its evil people just as a furnace removes the impurities (or rust) of iron."
