I have always advocated the reopening of the Hagia Sophia Mosque and will continue to do so.
The reason for this is very simple and clear. Because Hagia Sophia is the sword right of Sultan Mehmet, the conqueror of Constantinople, and it was dedicated as a mosque by Fatih Sultan Mehmet. This cannot be changed until doomsday. Nobody has the right and authority to change this.
Unfortunately, it has been turned into a museum by the heedless, who do not fear of Allah and do not know the law.
