Prayer behind an innovator imam?

Question:
The questioner asks: What is the ruling on praying behind an imam who believes that the Messenger of Allah (peace and blessings be upon him) fulfills needs?

Answer:
That is, in his state of death, he fulfills needs while he is dead. This is shirk (associating partners with Allah) with Allah (Mighty and Majestic), and the prayer behind him is not valid, because his prayer is not valid, as he is a mushrik (one who associates partners with Allah). The one who believes that the Messenger fulfills the needs of people after his death is committing shirk. Or, other than the Messenger (peace and blessings be upon him), among the dead: the dead person does not fulfill any of the affairs of people, nor does he fulfill needs, nor does he give or take, because he is dead.
And supplicating to the dead and asking them for needs is shirk. If this imam has this characteristic, he is a mushrik. His prayer is not valid, and the prayer of anyone behind him is not valid.
