Surat Al-'An`ām - سورة الأنعام

فَلَوْلَا إِذْ جَاءَهُم بَأْسُنَا تَضَرَّعُوا وَلَٰكِن قَسَتْ قُلُوبُهُمْ وَزَيَّنَ لَهُمُ الشَّيْطَانُ مَا كَانُوا يَعْمَلُونَ

Muhsin Khan: When Our Torment reached them, why then did they not believe with humility? But their hearts became hardened, and Shaitan (Satan) made fair-seeming to them that which they used to do.
