فَلَوْلَآ إِذْ جَآءَهُم بَأْسُنَا تَضَرَّعُوا۟ وَلَٰكِن قَسَتْ قُلُوبُهُمْ وَزَيَّنَ لَهُمُ ٱلشَّيْطَٰنُ مَا كَانُوا۟ يَعْمَلُونَ
How to read it
Falaw'lā 'idh' jā'ahum ba''sunā taḍarraʻū walākin qassat' qulūbuhum' wazayyana lahumu shshay'ṭānu mā kānū yaʻ'malūna
When the suffering reached them from us, why then did they not learn humility? On the contrary their hearts became hardened, and Satan made their (sinful) acts seem alluring to them.
Translation: Abdullah Yusuf Ali
