Surah Az-Zumar — Ayah 16 (39:16)
لَهُم مِّن فَوۡقِهِمۡ ظُلَلٞ مِّنَ ٱلنَّارِ وَمِن تَحۡتِهِمۡ ظُلَلٞۚ ذَٰلِكَ يُخَوِّفُ ٱللَّهُ بِهِۦ عِبَادَهُۥۚ يَٰعِبَادِ فَٱتَّقُونِ ١٦
English translation (Saheeh International)
They will have canopies [i.e., layers] of fire above them and below them, canopies. By that Allāh threatens [i.e., warns] His servants. O My servants, then fear Me.
Brief commentary
They will have the fire, extreme heat and smoke from above and beneath them there will be smoke, flames and heat. That punishment is what Allah warns His servants of. O My servants, so fear Me by fulfilling My instructions and avoiding My prohibitions.
