It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The days and nights will not come to an end, and even if only one day remained of the world, until Allah sends a man from my Ummah whose name matches my name."
