Etiquette of Entering Graveyards and Walking on Graves

Question:
This questioner asks, Shaykh: What are the etiquettes when entering graveyards? We observe in our current time actions that are not among these etiquettes, such as gathering in crowds, excessive talking, raising one's voice, and walking on the graves?

Answer:
The speech said at the graveyards is of two types. The speech of the visitor: when he visits the graves, he greets them just as he greets the living, saying, "Peace be upon you, O people of the graves, and the mercy of Allah and His blessings. O Allah, do not deprive us of their reward, and do not test us after them, and forgive us and them," or similar to what is reported in the hadiths.
As for the speech of those accompanying the funeral procession, they remember Allah the Exalted while walking, make supplication for the deceased, and seek forgiveness for him, but they do not raise their voices or make a collective noise as the innovators do, saying, "Unite your voices, say so-and-so, what do you say about so-and-so?"
All of this is from the newly invented speech. The companions of the funeral procession should only seek forgiveness for the deceased and make supplication for him without collective voices, and they should restrict themselves to the supplications that are prescribed and reported. It is not permissible to mistreat the graves by treading on them; it is not permissible to step on the graves, nor is it permissible to sit on the graves or insult them. Rather, they should be respected and avoided, and one should not trample on them, but rather walk between them. Yes.
