Whom to call upon.

Revile not ye those whom they call upon besides God, lest they out of spite revile God in their ignorance. Thus have We made alluring to each people its own doings. In the end will they return to their Lord, and We shall then tell them the truth of all that they did. ~ Surah Anam 108

"But those ye call upon besides Him, are unable to help you, and indeed to help themselves." ~ Surah Araf 197

For Him (alone) is prayer in Truth: any others that they call upon besides Him hear them no more than if they were to stretch forth their hands for water to reach their mouths but it reaches them not: for the prayer of those without Faith is nothing but (futile) wandering (in the mind). ~ Surah Rad 14

Say: "Call upon other (gods) whom ye fancy, besides God: They have no power,- not the weight of an atom,- in the heavens or on earth: No (sort of) share have they therein, nor is any of them a helper to God. ~ Surah Saba 22

Say: "Have ye seen (these) ’Partners’ of yours whom ye call upon besides God? Show Me what it is they have created in the (wide) earth. Or have they a share in the heavens? Or have We given them a Book from which they (can derive) clear (evidence)?- Nay, the wrong-doers promise each other nothing but delusions. ~ Surah Fatir 40

When My servants ask thee concerning Me, I am indeed close (to them): I listen to the prayer of every suppliant when he calleth on Me: Let them also, with a will, Listen to My call, and believe in Me: That they may walk in the right way. ~ Surah Baqarah 186
