if you call upon them they cannot hear your prayer. and if they hear it they cannot answer it. on the day of resurrection they will disown you for associating others with allah in his divinity. no one can inform you of the truth save the allaware.
إن تدعوهم لا يسمعوا دعاءكم ولو سمعوا ما استجابوا لكم ويوم القيامة يكفرون بشرككم ولا ينبئك مثل خبير
