Visiting the Grave of the Prophet salalahu 'alayhi wa sallam

[WM]

as-Salamu 'alaykum,

Akhi Abuz Zubair, could you give a post detailing the issue of visiting the Grave of the Prophet- salallahu 'alayhi wa sallam- with niyya (intention) according to the math-hab of the Hanabila (if no-one else in addition)?

[WM]

As well, they claim that in al-Mughni ibn Qudama allows you to make du'a directly to the Prophet- salallahu 'alayhiw a sallam- for intercession. They also say that ibn Taymiyya said that such a du'a was bid'a, not shirk.
