Insha'Allah we will see the appearance of the Mahdi (pbuh) and the Jesus Messiah (pbuh). We will see the intellectual annihilation of the system of the dajjal(antichrist). We will see the establishment of the Unity of Islam. And after that, Islam will start regressing. Regression will continue after Hijri 1506 until Hijri 1543. After Hijri 1543, only godless, bookless people will be left behind. And about Hijri 1545 by the leave of Allah the Last Day will come. - Harun Yahya
