Quran 39:16 from Surah Az-Zumar on Divine Marvels.
لَهُم مِّن فَوۡقِهِمۡ ظُلَلٞ مِّنَ ٱلنَّارِ وَمِن تَحۡتِهِمۡ ظُلَلٞۚ ذَٰلِكَ يُخَوِّفُ ٱللَّهُ بِهِۦ عِبَادَهُۥۚ يَٰعِبَادِ فَٱتَّقُونِ
English translation: For them from above them coverings of the Fire and from below them coverings (With) that threatens Allah [with it] His slaves O My slaves! So fear Me
Transliteration: lahum min fawqihim zulalun mina al-nari wamin tahtihim zulalun dhalika yukhawwifu al-lahu bihi ibadahu ya'ibadi fa-ittaquni
