Re: When a pious person died they make a place of worship at his grave
You need to look for ways of getting rid of the sins of the dead not asking them to get rid of yours!!!
Abu Hurayrah reported that a man said to the Prophet (peace and blessings of Allaah be upon him): “My father has died and left money behind. He did not make a wasiyyah (a will); will it expiate for his sins if I give some of it in charity on his behalf?” He said, “Yes.”
