وَلَقَدْ ضَرَبْنَا لِلنَّاسِ فِي هَٰذَا الْقُرْآنِ مِنْ كُلِّ مَثَلٍ ۚ وَلَئِنْ جِئْتَهُمْ بِآيَةٍ لَيَقُولَنَّ الَّذِينَ كَفَرُوا إِنْ أَنْتُمْ إِلَّا مُبْطِلُونَ 58
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."
