It is mentioned that Islam will be spread to all corners of the world in the state of Imam Mahdi (PBUH). But, how will the buildings, streets, and shops be? Will the style of construction change? Most of the buildings in Europe and America are built in European and American style, and even some of the houses in Arab countries are built in this style. Will Imam Mahdi (PBUH) change the style of building houses or streets and shops and make them built in the Islamic style, because there are houses in the Islamic style? Or will Imam Mahdi not order to change these things as long as they do not affect religion? Or will he change them as long as Islam spreads, even the buildings, shops, and streets will change to an Islamic style? Or are the narrations silent about these matters and did not mention them? Or is there no difference between the Islamic style of construction and the European or American style? I want a specific answer about this thing, so what is your opinion?
