وَلَقَدۡ ضَرَبۡنَا لِلنَّاسِ فِي هَٰذَا ٱلۡقُرۡءَانِ مِن كُلِّ مَثَلٖۚ وَلَئِن جِئۡتَهُم بِـَٔايَةٖ لَّيَقُولَنَّ ٱلَّذِينَ كَفَرُوٓاْ إِنۡ أَنتُمۡ إِلَّا مُبۡطِلُونَ

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."

— Ar-Rum (ٱلرُّوم), 30:58
