Visiting Dargah Qadam Rasool Shrines
It is not outright shirk but an innovation in religion which should be avoided at all costs since there is no basis in Quran or Sunnah to prove this point and also it goes against the clear boundaries of Dua acceptance as mentioned in Quran. Secondly, such shrines usually take a part in giving rise to polytheistic attitudes which may ultimately lead to polytheism which is another reason to avoid visiting such places with this particuler belief as mentioned in the question.
