According to Sunni Muslims, it is forbidden to raise tombs on graves as the Prophet (salallahu alayhi wassalam) had ordered to level the graves as reported in several authentic narrations [1][2][3].(http://www.sunnah.com/urn/1072140)
That is why Sunni scholars of the area of Najd suggested that the graves should be leveled and the muslim ruler in authority carried it out after he made the decision. So, the decision was of the ruler and not of the scholars. They merely suggested and advised based upon the Sunnah.
Is the ruling on Prophet's grave different?
No, not at all. The shar'i ruling is clear that all graves without any exception should be leveled, no matter whose grave it is. Several scholars have passed fataawa that it is not permissible to have the tomb over the Prophet's grave including al-Lajnah al-Daa’imah. So this is clear.
Then why is it not demolished?
As, I told you before, it is upon the muslim authority to demolish it. The scholars have explained the shar’i rulings concerning the building of this dome. However, there are many people who are not aware of this prohibition in Islam and are emotionally attached to this dome. Moreover, there are many innovators who misguide people to venerate this dome and attach sanctity to it. Now, these ordinary people get upset when they see the domes getting destroyed though it is according to the Sharee'ah. These misguided Imaams incite the ordinary people against the muslim authorities. So, in order to ward off chaos and fitnah, it has not been destroyed yet. Because, destroying it will cause a chaos among people which might lead to greater corruption.
This is similar to the event where a beduoin urinated inside the mosque and the Prophet(salallahu alayhi wassalam) stopped the people when they went to beat him. Thus, a greater evil is prevented by bearing a lesser one. The ruler of the kingdom has postponed its demolition till the time when situation gets better.
I hope it will be demolished by the authorities in the kingdom according to what the Prophet (salallahu alayhi wassalam) ordered, by the will of Allah.
