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."
The Saheeh International Quran Translation
وَلَقَدْ ضَرَبْنَا لِلنَّاسِ فِى هَٰذَا ٱلْقُرْءَانِ مِن كُلِّ مَثَلٍ وَلَئِن جِئْتَهُم بِـَٔايَةٍ لَّيَقُولَنَّ ٱلَّذِينَ كَفَرُوٓا۟ إِنْ أَنتُمْ إِلَّا مُبْطِلُونَAnd 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."
