The way of the Mahdi will put them right. That is no problem. I mean, if any errors are being made, it will correct them. Hazrat Mahdi (as) and the Prophet Jesus (as) will design the whole world. Both Hazrat Mahdi (as) and the Prophet Jesus (as) are expert architects. Both are also expert artists, with a fine knowledge of art. They will give it the most beautiful appearance. As you know, Hazrat Khidr (as) is also an architect, a teacher, insha’Allah. He also has an excellent understanding of art. Imagine a picture of the world in the 2030s. You will be amazed at the speed. “When did these districts appear?” “When did this beauty appear?” and “How quickly this all happened,” you will say.
