Quran 66:6 from Surah At-Tahrim on Divine Marvels.
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ قُوٓاْ أَنفُسَكُمۡ وَأَهۡلِيكُمۡ نَارٗا وَقُودُهَا ٱلنَّاسُ وَٱلۡحِجَارَةُ عَلَيۡهَا مَلَٰٓئِكَةٌ غِلَاظٞ شِدَادٞ لَّا يَعۡصُونَ ٱللَّهَ مَآ أَمَرَهُمۡ وَيَفۡعَلُونَ مَا يُؤۡمَرُونَ
English translation: O (you) who believe Protect yourselves and your families (from) a Fire whose fuel (is) people and stones over it (are) Angels stern severe not they disobey Allah (in) what He Commands them but they do what they are commanded
