Ar-Ra'd 13:14

لَهُۥ دَعۡوَةُ ٱلۡحَقِّۚ وَٱلَّذِينَ يَدۡعُونَ مِن دُونِهِۦ لَا يَسۡتَجِيبُونَ لَهُم بِشَيۡءٍ إِلَّا كَبَٰسِطِ كَفَّيۡهِ إِلَى ٱلۡمَآءِ لِيَبۡلُغَ فَاهُ وَمَا هُوَ بِبَٰلِغِهِۦۚ وَمَا دُعَآءُ ٱلۡكَٰفِرِينَ إِلَّا فِي ضَلَٰلٖ 14

And those they call upon besides Him do not respond to them with a thing, except as one who stretches his hands toward water [from afar, calling it] to reach his mouth, but it will not reach it [thus]. And the supplication of the disbelievers is not but in error [i.e. futility]
