وَقَالُوا لَوْلَا أُنزِلَ عَلَيْهِ مَلَكٌ ۖ وَلَوْ أَنزَلْنَا مَلَكًا لَّقُضِيَ الْأَمْرُ ثُمَّ لَا يُنظَرُونَ

Wa qaaloo law laaa unzila alaihi malakunw wa law anzalna malakal laqudiyal amru summa laa yunzaroon

Translation / The Meaning

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