The type of intercession (shafa'ah) by the living for the dead that is permissible at graves

Question:
May Allah reward you, Honorable Shaykh. This questioner says: I found a statement by Shaykh al-Islam in the book al-Iqtida' where he says: "Among the miracles (karamat) and supernatural events that occur at the graves of the awliya (close friends of Allah) is the intercession of some of them for their deceased brothers." The question is: What is the type of this intercession? And does it have a sound basis in the Book and the Sunnah? He says: "Among the miracles and supernatural events that occur at the graves of the awliya is the intercession of some of them for their deceased brothers."

Answer:
Yes, this visitor, the visitor intercedes for the dead by making supplication for them; he prays for them. This is the meaning of intercession: you pray for the deceased for forgiveness. This is intercession. Yes, it is what the living person intends for the deceased. The living person, the visitor, when he prays for the deceased, he has interceded for him.
