What is the ruling on collective supplication at the grave of the deceased?

Question:
He says that in our country, when they bury the deceased, one person stands and makes supplication at his grave, and the rest say "Ameen."

Answer:
We say that what is prescribed is that when Muslims bury the deceased, they stand at his grave and supplicate for him with mercy and forgiveness. It is not done collectively; rather, each person supplicates for himself. They do not form a group with one voice, nor does one person supplicate while the others say "Ameen." This has not been transmitted. Rather, you stand at the grave of your brother after the burial and say, "O Allah, forgive him. O Allah, grant him steadfastness." The next person says the same, and so on, without a collective voice or one person supplicating while the others say "Ameen." These are characteristics that have not been transmitted in this matter. The matter is that one supplicates for him without gathering, without a collective voice, and without following one person while the others say "Ameen" to his supplication. Yes.
