Is the Sunnah in praying over the deceased in the cemetery before he is placed in the grave?

Question:
He says: Honorable Shaykh, may Allah grant you success, is the Sunnah in praying over the deceased in the cemetery, or is it before he is placed in the grave, or is it after the burial?

Answer:
As long as he has not been buried, pray over him before he is placed in the grave. But if he has been placed in the grave, do not go out in order to pray over him; rather, bury him and pray over the grave. As long as he has not been lowered into the grave, if you pray over him outside, that is the news. Yes.
