A lot of christians like to say it was a wrath of god that the thunder hit our prophet's mosque in 1481 , what would be a good comeback to them and why did allah allow this to happen? My explanation is that something even worst could have happened which would have destroyed the whole mosque instead killing a lot of people, so allah sent the lighting so when its re-innovated it becomes stronger, it even has better artistic value aswell now
