وَمَا نُرْسِلُ الْمُرْسَلِينَ إِلَّا مُبَشِّرِينَ وَمُنذِرِينَ وَيُجَادِلُ الَّذِينَ كَفَرُوا بِالْبَاطِلِ لِيُدْحِضُوا بِهِ الْحَقَّ وَاتَّخَذُوا آيَاتِي وَمَا أُنذِرُوا هُزُوًا
[18:56]
And We do not send messengers but as givers of good news and warning, and those who disbelieve make a false contention that they may render null thereby the truth, and they take My communications and that with which they are warned for a mockery.
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!
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.
