What is the ruling regarding people who built a shrine for a man after his death, who used to teach the memorization of the Qur'an?

Question:
His message is somewhat long. He says that in the village where I live, there was a man who opened a book for teaching the memorization of the Qur'an for a fee, knowing that he had three sons who memorize the Book of Allah. This man took a room next to the Qur'an memorization office, where he practiced preparing the men, women, and children of the village with the Qur'an and the hizb (portions of the Qur'an). This man passed away, and after a year had passed since his death, one of the residents told us, "I saw so-and-so"—meaning this man who died a full year ago—in a dream, in which this deceased person requested that his body be moved from his burial place to the place where he used to practice. Knowing that the grave in which he was buried is three kilometers away from our village. The body was indeed moved to the place he was commanded to be moved to. And they built a shrine for this man. All the residents of the village, men and women, visit it. And they took for him

Answer:
We have issued a ruling, may Allah reward you with good and bless you, on this issue from all its angles. This is an invalid act, and it is not permissible to act upon this vision, because it is a vision from Shaytan. Burying the deceased in the mosque or in the room adjacent to the mosque is not permissible, because this is one of the means to shirk (associating partners with Allah). The Prophet (peace and blessings be upon him) forbade building mosques over graves, and forbade taking graves as mosques, meaning praying at them, whether a building is constructed over them or not, because that is one of the means to shirk. As for the intention of visiting the shrine to seek healing through the deceased, or to ask him to fulfill needs, or to ward off harm, or to bring about good, that is major shirk, may Allah protect us from it. This is major shirk. The reason for this, the reason for the occurrence of this major shirk, is burying the deceased or moving him to this place and building this shrine for him. Because building shrines, building over graves, burying them in mosques, or building mosques over them, or praying at them, all of these are means to shirk.
Therefore, when this deceased person was moved to this place at the mosque or adjacent to the mosque, the people turned to him, directing worship to him other than Allah (Mighty and Majestic). This is an invalid act, and it is obligatory to dig up this deceased person and take him out of this place and bury him in the cemetery, burying him in the cemetery with the other deceased in the cemetery. It is not permissible to bury him in the mosque. He must be returned to his original grave, which was far from the mosque. Yes. May Allah reward you with good, and may Allah do you good.
