Riyaadul Jannah

Q: It was narrated from Abu Hurayrah that Muhammad (Sallallahu Alayhi Wasallam) said: "The area between my house and my minbar is one of the gardens (rawdah) of Paradise, and my minbar is on my cistern (hawd).

My question is that that will that part of earth be raised into jannah its a duplicate of that part of earth?

Also I heard its shirk to dua from other poeple I mean like you trust into them. Or making dua though someone. Please shed some light on this topic with the opinion of the hanafi maddhab.
