Maulwi Ashraf Ali Thanwi writes:
"Seeking assistance from other than Allah عزوجل (Istiaanat and Istimdaad) made with the belief that the person (to whom it was made) has knowledge, power and is mustaqil (permanent) is polytheism. If help was asked without the belief of knowledge and power and the person asked is believed to be non-permanent (Ghair-Mustaqil), with his knowledge and power having been proven through a proof, then this is allowed, irrespective of whether the person beseeched is alive or has passed away."
-lmdaadul-Fataawa, Vol. 4, Pg.99
He has decided that asking for help (istimdaad) made to the creation is permissible with the acceptance that he has non-permanent power, even if help is asked from a person who has passed away.
