Sura al-Mulk 67:9

قَالُوا۟ بَلَىٰ قَدْ جَآءَنَا نَذِيرٌ فَكَذَّبْنَا وَقُلْنَا مَا نَزَّلَ ٱللَّـهُ مِن شَىْءٍ إِنْ أَنتُمْ إِلَّا فِى ضَلَٰلٍ كَبِيرٍ

qālū balā qad jāʾanā nadhīrun fa-kadhdhabnā wa-qulnā mā nazzala allāhu min shayʾin in antum illā fī ḍalālin kabīrin

They will say: "Yes indeed; a Warner did come to us, but we rejected him and said, 'Allah never sent down any (Message): ye are nothing but an egregious delusion!'"
