Assalamu Alaikkum wa rahamatullahi wa barakatuhu,
I wanted to share something about this. I would consider some relic like this as a fitnah in itself. Agreed, we don't see anything in this video that might be Shirk. But, yesterday I was watching a documentary about Afghanistan. In that, An "Imam" of the mosque in Kandhar was saying that the mosque has the Prophet (sallallahu alayhi wasallam)'s mantle which is a relic. And people worship the Prophet(sallallahu alayhi wasallam)'s mantle because it is sacred and holy etc. Astagfirullah! And when Muhammad Omar (Taliban) removed the mantle from the mosque, they considered it a big blasphemy.
That is the reason why I consider something like this as a fitnah atleast among people who don't know the aqeedah properly.
