Nothing like this: wormwood (Niburu); but the incidents of Doomsday have been explained in details by the Mahdi in the second part of his book The Universe and the Quran
The past prophets only warned of the coming Doomsday, and they described its woes and calamities. While the Mahdi describes it in details and explains how this Doomsday will occur and why; because the Mahdi is very near to Doomsday in time. And his time is the time of science, so that people can understand how Doomsday will occur according to the Quran and its interpretation.
