Surah Al-An'am, ayah 8

وَقَالُواْ لَوۡلَآ أُنزِلَ عَلَيۡهِ مَلَكٞۖ وَلَوۡ أَنزَلۡنَا مَلَكٗا لَّقُضِيَ ٱلۡأَمۡرُ ثُمَّ لَا يُنظَرُونَ ٨

Waqālū lawlā unzila 'alayhi malakun walaw anzalnā malakal laqudiyal-amru thumma lā yunzarūn

And they say, "Why was there not sent down to him an angel?"²⁹⁴ But if We had sent down an angel, the matter would have been decided;²⁹⁵ then they would not be reprieved.
