Surah Ar-Rum · Ayah 58

وَلَقَدْ ضَرَبْنَا لِلنَّاسِ فِى هَٰذَا ٱلْقُرْءَانِ مِن كُلِّ مَثَلٍۢ ۚ وَلَئِن جِئْتَهُم بِـَٔايَةٍۢ لَّيَقُولَنَّ ٱلَّذِينَ كَفَرُوٓا۟ إِنْ أَنتُمْ إِلَّا مُبْطِلُونَ

Wa laqad darabnaa linnaasi fee haazal Quraani min kulli masal; wa la'in ji'tahum bi aayatil la yaqoolannal lazeena kafaroo in antum illaa mubtiloon

And We have certainly presented to the people in this Qur'an from every [kind of] example. But, [O Muhammad], if you should bring them a sign, the disbelievers will surely say, "You [believers] are but falsifiers."
