What will happen to the world after the Prophet Jesus (pbuh) and Hazrat Mahdi (as) pass away?

ADNAN OKTAR: In the End Times, after Jesus Messiah and Mahdi (as) pass away, Gog and Magog will invade the world. A communist counter-movement will surge in response to the invasion in 1543 Hijri. Communists will reign for two or three years. And after that the world will be destroyed. In other words, the Day of Judgment will come. Our Prophet (saas) says in a hadith that, "people will fornicate with their mothers in public like donkeys, and upon them the Hour will come." There will be a handful of believers left, and God will take their lives away just before the Hour comes.
