Recently, there has been visitors of Imam Hussain (as) who dress up as animals (lions), to either represent the enemies of Ahlul Bayt (as), or to show that animals mourn as well for the tragedy of the Ahlul Bayt (as).

What is Sayed Ali Sistani’s fatwa regarding this act?
And if Sayed Ali Sistani hasn’t done any fatwa concerning this, then what are the opinions of other scholars?

This is done to remember the lion Harith who came to protect the Imams body
