Translation of the verse 56 from Surah Al-Isra’ : Number of verses 111 - - page 287 - Part 15.
Say (O Muhammad SAW): "Call unto those besides Him whom you pretend [to be gods like angels, Iesa (Jesus), 'Uzair (Ezra), etc.]. They have neither the power to remove the adversity from you nor even to shift it from you to another person."
Say, "Invoke those you have claimed [as gods] besides Him, for they do not possess the [ability for] removal of adversity from you or [for its] transfer [to someone else]."
(17:56) Say to them, "You may invoke for help those deities whom you consider to be (your helpers) beside Allah: They will not be able to relieve you of any trouble nor change it. " *64
*64) This warning helps to elaborate the Doctrine of Tauhid and negate shirk. According to this, shirk is not confined merely to falling prostrate before any other than Allah but it is also shirk to pray to or invoke the help of any other than AIIah; for praying to or calling for help any other than Allah is in reality a kind of worship. Therefore, the one who invokes for help any other than Allah is as much guilty of shirk as the worshipper of an idol. This verse also shows clearly that none other than Allah has any power to attend to prayers and relieve any one of trouble or alter any one's bad condition. Hence, if one believes that some one other than Allah has any power, he shall be guilty of shirk.
