Is it permissible to make collective supplication and raise the hands when making du'a' for the deceased after burial?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Is it permissible to make du'a' for the deceased after burial by raising one's hands, or is the du'a' collective behind a single supplicant?

Answer:
Collective, no. As for raising the hands, yes, there is no harm. He raises his hands and makes du'a' for the deceased and seeks forgiveness for him, but collective, no. Yes.
