arsh

Sand touching the Mubaarak Body of Rasulullah (Sallallahu Alayhi Wasallam) being more superior than the arsh

Q: I was recently asked by somebody that Hazrat Shaikh in Fazaail-e-Haj says that the sand touching the Mubaarak body of Rasoolullaah صلى الله عليه وسلم is more superior to the arsh, the question being is it possible for anything to be more superior over the arsh?
