Sayyiduna Abu Hurayrah (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) said: "The Hour will not be established until you wage jihad against Khuz and Kirman, non-Arab peoples with red faces, flat noses and small eyes, as though their faces were shields layered one upon another."
