Quran 43:24 from Surah Az-Zukhruf on Divine Marvels.
۞قَٰلَ أَوَلَوۡ جِئۡتُكُم بِأَهۡدَىٰ مِمَّا وَجَدتُّمۡ عَلَيۡهِ ءَابَآءَكُمۡۖ قَالُوٓاْ إِنَّا بِمَآ أُرۡسِلۡتُم بِهِۦ كَٰفِرُونَ
English translation: He said Even if I brought you better guidance than what you found on it your forefathers They said Indeed we with what you are sent with [it] (are) disbelievers
Transliteration: qala awalaw ji'tukum bi-ahda mimma wajadttum alayhi abaakum qalu inna bima ur'sil'tum bihi kafiruna
