It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "Soon my Ummah will be afflicted by the disease of the earlier nations." The Companions said: "O Messenger of Allah! What is the disease of the earlier nations?" He (peace and blessings be upon him) said: "Ingratitude, excessive exultation, greed for amassing wealth, deceiving one another in worldly matters, mutual hatred and envy, until transgression and oppression arise."
