A muslim who prayes at the grave or dargah is doing so because of his lack of islamic knowledge. Muslims pray FACING the KABAA which is the House of Lord Almighty but it still remains a house made of brick and mud and stone and will be destroyed like anyother object on the day of judgement. This is a belief of a muslim. The only remaining thing will be The presence of Almighty and HE alone is worthy of worship.
It is really strange you find it ackward the way of a prophet but still your fellow co-faithist are fighting on rubble of fallen mosques and decaying bridges somewhere in the ocean. You first ask them to get out of ignorance before commenting on the most influential personality humanity has ever known.
