فَلَوۡلَآ إِذۡ جَآءَهُم بَأۡسُنَا تَضَرَّعُواْ وَلَٰكِن قَسَتۡ قُلُوبُهُمۡ وَزَيَّنَ لَهُمُ ٱلشَّيۡطَٰنُ مَا كَانُواْ يَعۡمَلُونَ ٤٣
Then why, when Our punishment came to them, did they not humble themselves? But their hearts became hardened, and Satan made attractive to them that which they were doing.
Translation: Saheeh International (English)
Each word's meaning and sound
If only they had humbled themselves before Allah, when His calamity came to them, and begged Allah to remove the calamity, then He would have shown them mercy. But they did not do that. Instead, their hearts became hard and they did not take notice and learn a lesson. Satan made the disbelief and sins that they were committing seem good to them, so they continued with those actions.
