When Islam prevails, one who attains a million good deeds would only attain one good deed. Someone who previously attained a million good deeds with an act, with a behavior, would only attain –let us say- five good deeds with that act when Islam prevails in the whole world. After that, because no meaning is left in life and because the trial has come to an end, the Last Day comes swiftly. The passing away of Hazrat Mahdi (pbuh) and the prophet Jesus Messiah (pbuh) and then the Last Day will come rapidly, insha'Allah. - Harun Yahya
