Quran verses about Parables in the Quran

لَهُۥ دَعْوَةُ ٱلْحَقِّ وَٱلَّذِينَ يَدْعُونَ مِن دُونِهِۦ لَا يَسْتَجِيبُونَ لَهُم بِشَىْءٍ إِلَّا كَبَٰسِطِ كَفَّيْهِ إِلَى ٱلْمَآءِ لِيَبْلُغَ فَاهُ وَمَا هُوَ بِبَٰلِغِهِۦ وَمَا دُعَآءُ ٱلْكَٰفِرِينَ إِلَّا فِى ضَلَٰلٍ ۝١٤

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]. And the supplication of the disbelievers is not but in error [i.e., futility].

مَثَلُ ٱلَّذِينَ ٱتَّخَذُوا۟ مِن دُونِ ٱللَّهِ أَوْلِيَآءَ كَمَثَلِ ٱلْعَنكَبُوتِ ٱتَّخَذَتْ بَيْتًا وَإِنَّ أَوْهَنَ ٱلْبُيُوتِ لَبَيْتُ ٱلْعَنكَبُوتِ لَوْ كَانُوا۟ يَعْلَمُونَ ۝٤١

The example of those who take allies other than Allāh is like that of the spider who takes [i.e., constructs] a home. And indeed, the weakest of homes is the home of the spider, if they only knew.
