Quran 6:8 Al-An'am, ayah 8 of 165

وَقَالُوا۟ لَوْلَآ أُنزِلَ عَلَيْهِ مَلَكٌ ۖ وَلَوْ أَنزَلْنَا مَلَكًا لَّقُضِىَ ٱلْأَمْرُ ثُمَّ لَا يُنظَرُونَ ۝٨

6:8 They say: Why hath not an angel been sent down unto him? If We sent down an angel, then the matter would be judged; no further time would be allowed them (for reflection).
