Amr bin Harith narrates that once Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) became ill. When he recovered, he came out to meet the people, apologized to them, and said, "We only desire good." Then he said that the Messenger of Allah (peace and blessings be upon him) narrated this hadith to us: "The Dajjal will emerge from an eastern region called 'Khurasan,' and people will follow him whose faces will be like flat shields."
