وَمَا نُرۡسِلُ ٱلۡمُرۡسَلِينَ إِلَّا مُبَشِّرِينَ وَمُنذِرِينَۚ وَيُجَٰدِلُ ٱلَّذِينَ كَفَرُواْ بِٱلۡبَٰطِلِ لِيُدۡحِضُواْ بِهِ ٱلۡحَقَّۖ وَٱتَّخَذُوٓاْ ءَايَٰتِي وَمَآ أُنذِرُواْ هُزُوٗا

Wa maa nursilul mursaleena illaa mubashshireena wa munzireen; wa yujaadilul lazeena kafaroo bilbaatili liyudhidoo bihil haqqa wattakhazooo Aayaatee wa maaa unziroo huzuwaa

We only send the messengers to give Glad Tidings and to give warnings: But the unbelievers dispute with vain argument, in order therewith to weaken the truth, and they treat My Signs as a jest, as also the fact that they are warned!

— Al-Kahf (ٱلْكَهْف), 18:56
