Defects in Creed and Visiting Graves

Question:
This man is also asking, and he says, may Allah preserve you. What are the defects in Islamic creed? Knowing that I see some customs and traditions in our country, such as visiting graves and greeting the deceased, as well as making du'a' (supplication) and asking for du'a' from them, and also placing large stones on their graves.

Answer:
Without a doubt, visiting graves is of two types: a lawful visit and a visit involving shirk (associating partners with Allah). The lawful visit is that in which one intends to greet the deceased and make du'a' for him. As for the visit involving shirk, it is that in which one intends to call upon the dead and ask the dead for one's needs. This is a visit involving shirk; it is a visit involving major shirk that expels one from the religion, in which one calls upon the dead and asks them for needs and requests. There is no doubt that this is an invalid visit involving shirk, and it invalidates one's religion, may Allah protect us from it, and one joins the ranks of the mushrikin (those who associate partners with Allah). Yes.
