Can He Know That a Visitor Is at His Grave?

This is a very theological question that even the sahaba differed over. And this incident of bede is one of the most important evidences used by both sides. Is an authentic evidence. Everybody knows it is there. The interpretation is the issue. Ah, can he know that a visitor is at his grave? This is a very theologian-based debate. It's not relevant to the point. The point here is that iben rumar affirmed htthe dead can hear the wailing. Eben ruma affirmed the dead can hearing the wailing."
