Surah Az-Zukhruf, Verse 24

۞ قَٰلَ أَوَلَوۡ جِئۡتُكُم بِأَهۡدَىٰ مِمَّا وَجَدتُّمۡ عَلَيۡهِ ءَابَآءَكُمۡۖ قَالُوٓاْ إِنَّا بِمَآ أُرۡسِلۡتُم بِهِۦ كَٰفِرُونَ٢٤

qāla awalaw ji'tukum bi-ahdā mimmā wajadttum ʿalayhi ābāakum qālū innā bimā ur'sil'tum bihi kāfirūna

[Each warner] said, "Even if I brought you better guidance than that [religion] upon which you found your fathers?" They said, "Indeed we, in that with which you were sent, are disbelievers."
