74:31
وَمَا جَعَلۡنَاۤ أَصۡحَـٰبَ ٱلنَّارِ إِلَّا مَلَـٰۤىِٕكَةࣰۖ وَمَا جَعَلۡنَا عِدَّتَهُمۡ إِلَّا فِتۡنَةࣰ لِّلَّذِینَ كَفَرُوا۟ لِیَسۡتَیۡقِنَ ٱلَّذِینَ أُوتُوا۟ ٱلۡكِتَـٰبَ وَیَزۡدَادَ ٱلَّذِینَ ءَامَنُوۤا۟ إِیمَـٰنࣰا وَلَا یَرۡتَابَ ٱلَّذِینَ أُوتُوا۟ ٱلۡكِتَـٰبَ وَٱلۡمُؤۡمِنُونَ وَلِیَقُولَ ٱلَّذِینَ فِی قُلُوبِهِم مَّرَضࣱ وَٱلۡكَـٰفِرُونَ مَاذَاۤ أَرَادَ ٱللَّهُ بِهَـٰذَا مَثَلࣰاۚ كَذَ ٰلِكَ یُضِلُّ ٱللَّهُ مَن یَشَاۤءُ وَیَهۡدِی مَن یَشَاۤءُۚ وَمَا یَعۡلَمُ جُنُودَ رَبِّكَ إِلَّا هُوَۚ وَمَا هِیَ إِلَّا ذِكۡرَىٰ لِلۡبَشَرِ ۝٣١

and We made only the angels guardians of the fire and We made their numbers (nineteen) only as a test for those who disbelieve, so that those who were given the book would be certain and to increase the belief of those who believe, and those who were given the book and the believers would not doubt, and so that those who have a disease in their hearts and the disbelievers say: “What did God intend with this example?” That is how God misguides anyone He wants and guides anyone He wants. And none knows God's soldiers except Him. And this is only a reminder for the human being.
