Is it permissible in Islam to exhume graves and remove remains from them?

The basic principle is that it is impermissible to exhume graves, in order to preserve the sanctity of the deceased. However, if there is a need that necessitates it, such as people becoming infatuated with the occupant of a grave and believing they can cause benefit or harm, then this is a necessity that permits the exhumation, relocation, and concealment of graves from the public. The interest here is a legitimate one, pertaining to the very foundation of religion, which is creed (Aqidah), because attachment to the graves of the righteous is a means to polytheism (shirk). The Companions concealed the grave of Prophet Daniel for this very purpose, as mentioned by Abu Al-Aliyah. This is contingent on the condition that this action does not result in a greater harm.
