Surah Fussilat, Verse 14

إِذۡ جَآءَتۡهُمُ ٱلرُّسُلُ مِنۢ بَيۡنِ أَيۡدِيهِمۡ وَمِنۡ خَلۡفِهِمۡ أَلَّا تَعۡبُدُوٓاْ إِلَّا ٱللَّهَۖ قَالُواْ لَوۡ شَآءَ رَبُّنَا لَأَنزَلَ مَلَٰٓئِكَةٗ فَإِنَّا بِمَآ أُرۡسِلۡتُم بِهِۦ كَٰفِرُونَ١٤

idh jāathumu l-rusulu min bayni aydīhim wamin khalfihim allā taʿbudū illā l-laha qālū law shāa rabbunā la-anzala malāikatan fa-innā bimā ur'sil'tum bihi kāfirūna
