Quran 41:14 from Surah Fussilat on Divine Marvels.
إِذۡ جَآءَتۡهُمُ ٱلرُّسُلُ مِنۢ بَيۡنِ أَيۡدِيهِمۡ وَمِنۡ خَلۡفِهِمۡ أَلَّا تَعۡبُدُوٓاْ إِلَّا ٱللَّهَۖ قَالُواْ لَوۡ شَآءَ رَبُّنَا لَأَنزَلَ مَلَٰٓئِكَةٗ فَإِنَّا بِمَآ أُرۡسِلۡتُم بِهِۦ كَٰفِرُونَ
English translation: When came to them the Messengers from before them from before them from before them and from behind them (saying) Do not worship but Allah They said If (had) willed our Lord surely, He (would have) sent down Angels So indeed, we in what you have been sent with (are) disbelievers
Transliteration: idh jaathumu al-rusulu min bayni aydihim wamin khalfihim alla ta'budu illa al-laha qalu law shaa rabbuna la-anzala malaikatan fa-inna bima ur'sil'tum bihi kafiruna
