Mu’adhah ‘Adawiyyah says that once I was present in the service of Hazrat ‘A’ishah (may Allah be pleased with her), so she said that the Prophet (peace and blessings be upon him) said:“My ummah will only be destroyed by spear fighting and plague.”I asked,“O Messenger of Allah! We understand the meaning of spear fighting, but what is meant by plague?”The Prophet (peace and blessings be upon him) said:“It is a swelling that resembles the swelling of a camel. Whoever remains steadfast in it will be like a martyr, and whoever flees from it will be like one who flees from the battlefield.”
