What is the ruling on instructing the deceased after burial?

Question:
The second issue is the issue of instructing the deceased. When the deceased is placed in the grave, or when he is buried, one person stands by him and says, "O so-and-so, son of so-and-so," until he says, "O so-and-so, son of so-and-so, son of so-and-so, remember what you came out of the world upon. You bear witness that there is no god but Allah," and so on. A hadith has been reported regarding this. A hadith has been reported regarding this, but it has no chain of narration.

Answer:
Its chain is not sound, and it is not to be relied upon; it is not to be relied upon. And if the deceased died upon faith, then Allah will make him firm, even if you did not come to instruct him. If he died upon faith, then Allah will make him firm. And the Prophet (peace and blessings be upon him) said, "As for the believer..." Muhammad (peace and blessings be upon him) does not need instruction as long as he is a believer, for Allah (Mighty and Majestic) will make him firm. And if he was a hypocrite, it will not benefit him, even if you instructed him night and day; it will not benefit him. He says, "Ha, ha, I do not know. I heard people saying something, so I said, 'You are of no benefit, and if he is a believer, he does not need it. And if he is a hypocrite, you are of no benefit to him. Your instruction does not help, and he does not know. He says, 'Ha, ha, I do not know.'"
There is no power or might except with Allah.
