Surah Ar-Rum (The Romans), Verse 58

وَلَقَدْ ضَرَبْنَا لِلنَّاسِ فِیْ هٰذَا الْقُرْاٰنِ مِنْ كُلِّ مَثَلٍ وَلَىِٕنْ جِئْتَهُمْ بِاٰیَةٍ لَّیَقُوْلَنَّ الَّذِیْنَ كَفَرُوْۤا اِنْ اَنْتُمْ اِلَّا مُبْطِلُوْنَ ۟

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

“verily We have propounded for men, in this Qur'an every kind of Parable: But if thou bring to them any Sign, the Unbelievers are sure to say, "Ye do nothing but talk vanities."”

Quran 30:58 (Yusuf Ali Translation)
