The suffering and horror in the world will keep on growing, right until the coming of the Mahdi is clear for all to see. There will be an unbelievable increase in pain and suffering everywhere, not just in the Islamic world in 2016 and 2017, and by 2018 there will literally be a hell on earth. But 2019, 2021 and 2023 will be years of salvation. - Harun Yahya
