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

The only true prayer is to Him: those they pray to besides Him give them no answer any more than water reaches the mouth of someone who simply stretches out his hands for it- it cannot do so: the prayers of the disbelievers are all in vain.
For Him (Allah, Alone) is the Word of Truth (i.e. none has the right to be worshipped but Allah). And those whom they (polytheists and disbelievers) invoke, answer them no more than one who stretches forth his hand (at the edge of a deep well) for water to reach his mouth, but it reaches him not; and the invocation of the disbelievers is nothing but an error (i.e. of no use).
