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 the sun rises from the west, and when the sun rises from the west, all the people will see it and believe; and that is the time when 'no soul will benefit from its faith if it had not believed before or earned good through its faith' [Surah al-An'am: 158]."
