What is the ruling on instructing the deceased after burial and delivering a sermon

The questioner : So, what is the ruling on instructing the deceased after his burial at the grave, or delivering a sermon at the grave, O Shaykh?

The Shaykh : Or the qish.

The questioner : A sermon at the grave so that the attendees, for example, may be admonished.

The Shaykh : Yes, instructing him after burial is a bid'ah (religious innovation). A hadith has been reported regarding it, but it is not authentic. What is prescribed after burial is for a person to stand, seek forgiveness for the deceased, and ask Allah for his steadfastness. He says: “O Allah, forgive him, O Allah, forgive him, O Allah, forgive him, O Allah, make him steadfast,” “O Allah, make him steadfast, O Allah, make him steadfast,” three times seeking forgiveness and three times supplicating for steadfastness, and then he departs. Yes. Yes, O Shaykh. As for the sermon, it is not part of the Sunnah, and it should not be done. Because the Prophet (peace and blessings be upon him), (may peace and blessings be upon him), who was the most eager of people for admonition, did not deliver sermons to people in the graveyards. Nor have we known that from the Rightly Guided Caliphs, nor have we known that from our previous scholars. Yes, if it were assumed that a man sat down.
waiting for the burial of the deceased, with a group around him, and he spoke to them about the state of dying, the state of a person after burial, and similar admonitions that soften hearts, that would be good. Because the Prophet (peace and blessings be upon him and his family) did so. He and his Companions arrived at a grave that had not yet been buried, so they sat waiting for the burial of the grave, and he spoke to them in ordinary conversation, not standing and delivering a sermon. There is no doubt that the best guidance is the guidance of Muhammad (peace and blessings be upon him). If we were to open this door, it would be possible for a preacher to stand up, a skilled orator, and then deliver a sermon to the people for half an hour or more, and the graveyards would remain as if they were mosques. And a person must restrict his emotion and his love for good to what the Prophet (peace and blessings be upon him) did.
