A musallee says that its not proven from any authentic hadith that Rasulullah Sallallahu Alaihi Wasallam recited Quran in the graveyard and if we do it, we must face Qibla and not face the qabr. Please reply with hadith if possible or some explanation that proves its permissible to recite Quran in the graveyard and we can face the qabr.

This person wont be satisfied with a simple answer so please give a detailed reply
