Government of Saudi Arabia made arrangements to display the household things owned by Prophet Muhammad PBUH. Those were displayed in the museum so that everybody could have the chance to witness those sacred things. Many people went there in the museum to see such sacred stuff. They all thanked the government of the county for enabling them to witness such stuff.
The video was also made by the people who had gone there to the museum to witness the sacred things. The video was watched by lots of people on the social media. Social media has become the medium for spreading lots of good stuff through internet. That video of those things was watched and shared by lots of people on the internet.
The idea behind showing that stuff into display was to make people watch the precious things. Some of the people said that it was a good idea so that many Muslims could watch that stuff.
