39:58
أَوْ تَقُولَ حِينَ تَرَى ٱلْعَذَابَ لَوْ أَنَّ لِى كَرَّةً فَأَكُونَ مِنَ ٱلْمُحْسِنِينَ
aw taqūla ḥīna tarā l-ʿadhāba law anna lī karratan fa-akūna mina l-muḥ'sinīna
Or, faced by punishment, it says, “If only I could have another chance, I would join those who do good!”
Or (lest) he should say when he sees the torment: "If only I had another chance (to return to the world), then I should indeed be among the Muhsinûn (good-doers - See V.2:112)."
