Both Hazrat Mahdi (pbuh) and the Prophet Jesus Messiah (pbuh) are master architects; they will redesign the whole world.
Excerpt from Mr. Adnan Oktar's Live Interview on A9 TV dated August 22nd, 2011
MS.BETUL: The Saudi King Abdullah made the openings of the projects he started five years ago in Mecca and Medina. Among those projects there are also some buildings that draped over the Kaaba. The clock tower with 55 storeys established over 230 thousand meter square land, 35 seven star hotel buildings from which Kaaba could be seen in the upper storeys are among those projects. And we also have a picture of this area Master, this is how it looks. As you have stated numerous times previously, Kaaba is seen in the picture being left in a small ground in the middle of all those buildings.
ADNAN OKTAR: The system of the Mahdi will rectify those places, he will correct them; that would not be a problem. I mean if there is a mistake done, he will correct it. Hazrat Mahdi and the Prophet Jesus Messiah (pbuh) will design the whole world insha'Allah. As a matter of fact, both of them, both Hazrat Mahdi (pbuh) and the Prophet Jesus Messiah (pbuh) are master architects. They both are masters of art who know art most perfectly. They will turn those places into the most pleasant form, the most beautiful form insha'Allah.
ADNAN OKTAR: Hazrat Khidr (pbuh), as you know, is also an architect, he also is a Master, insha'Allah. He also is a person who has an exquisite understanding of art. Picture the world of 2030's in your mind..
PRESENTER: It would be perfect insha'Allah.
ADNAN OKTAR: And you will be amazed by the speed. You would say; "My brother, when did these districts come into existence? When did these beauties come into existence?" You would be amazed saying "what a speed this is".
