Verse 56

وَمَا نُرْسِلُ ٱلْمُرْسَلِينَ إِلَّا مُبَشِّرِينَ وَمُنذِرِينَ وَيُجَـٰدِلُ ٱلَّذِينَ كَفَرُوا۟ بِٱلْبَـٰطِلِ لِيُدْحِضُوا۟ بِهِ ٱلْحَقَّ وَٱتَّخَذُوٓا۟ ءَايَـٰتِى وَمَآ أُنذِرُوا۟ هُزُوًا

And We do not send messengers except as bearers of good news as well as warners. As for the unfaithful, they argue with falsehood in order to defeat the truth, and they ridicule My proofs and My warnings
