Mu’adhah ‘Adawiyyah says that once I presented myself in the service of Hazrat Aisha (may Allah be pleased with her), and she said that the Prophet (peace and blessings be upon him) said:“My ummah will be destroyed by spear fighting and by plague.”I asked,“O Messenger of Allah! We understand what spear fighting means, 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.”
