Hadith 6838
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The Hour will not be established until the sun rises from the west. When it rises from the west, all people will believe, but on that day, the faith of no person will benefit him who did not believe before, or who did not earn any good through his faith."
