Is supplication for the dead a form of supplication in their absence?

Question:
For example, if someone makes supplication for distant deceased relatives who do not have close relatives present to make supplication for them, is that considered supplication in their absence? May Allah reward you. For instance, for his grandfather or grandmother?

Answer:
Supplication for the living and the dead is all supplication in their absence, provided they are not present. It is supplication in their absence, whether they are alive or dead. This is supplication in their absence: the living person if he is not present, and the dead person is known to be not present.
