لَهُم مِّن فَوْقِهِمْ ظُلَلٌ مِّنَ النَّارِ وَمِن تَحْتِهِمْ ظُلَلٌ ذَلِكَ يُخَوِّفُ اللَّهُ بِهِ عِبَادَهُ يَا عِبَادِ فَاتَّقُونِ
[39:16]
They shall have coverings of fire above them and coverings beneath them; with that Allah makes His servants to fear, so be careful of (your duty to) Me, O My servants!
They shall have Layers of Fire above them, and Layers (of Fire) below them: with this doth Allah warn off his servants: "O My Servants! then fear ye Me!"
They have an awning of fire above them and beneath them a dais (of fire). With this doth Allah appal His bondmen. O My bondmen, therefor fear Me!
