Question: There is a grave in our village which is said to belong to one of the righteous people. A house was built over this grave and there are two people appointed to take care of it. These people inherited this mission from their fathers. They tell people: “This night, the dweller of this grave said so and so and asked for so and so. They have attracted people’s hearts that live beside the grave. People believe everything that is said by these two people. Therefore, people make Tawaaf (circumambulation) around the grave, sacrifice animals for its sake, etc. What is the ruling on a person who thinks that this Walee (pious person) brings benefit or causes harm? Is it permissible to vow or sacrifice for the sake of this Walee? What should someone do if they know that these things contradict Sharee`ah (Islaamic law) especially if they live with these people?
