وَمَا نُرْسِلُ ٱلْمُرْسَلِينَ إِلَّا مُبَشِّرِينَ وَمُنذِرِينَ ۚ وَيُجَٰدِلُ ٱلَّذِينَ كَفَرُوا۟ بِٱلْبَٰطِلِ لِيُدْحِضُوا۟ بِهِ ٱلْحَقَّ ۖ وَٱتَّخَذُوٓا۟ ءَايَٰتِى وَمَآ أُنذِرُوا۟ هُزُوًۭا
We send not the messengers save as bearers of good news and warners. Those who disbelieve contend with falsehood in order to refute the Truth thereby. And they take Our revelations and that wherewith they are threatened as a jest.
Surah Al-Kahf(18:56)
