Ar-Ra'd 13:14

لَهُۥ دَعْوَةُ ٱلْحَقِّ ۖ وَٱلَّذِينَ يَدْعُونَ مِن دُونِهِۦ لَا يَسْتَجِيبُونَ لَهُم بِشَىْءٍ إِلَّا كَبَـٰسِطِ كَفَّيْهِ إِلَى ٱلْمَآءِ لِيَبْلُغَ فَاهُ وَمَا هُوَ بِبَـٰلِغِهِۦ ۚ وَمَا دُعَآءُ ٱلْكَـٰفِرِينَ إِلَّا فِى ضَلَـٰلٍ

Lahu daʿwatu l-ḥaqi wa-alladhīna yadʿūna min dūnihi lā yastajībūna lahum bishayin illā kabāsiṭi kaffayhi ilā l-māi liyablugha fāhu wamā huwa bibālighihi wamā duʿāu l-kāfirīna illā fī ḍalālin

To Him [alone] is the supplication of truth. 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].¹ And the supplication of the disbelievers is not but in error [i.e., futility].
