سُورَةُ الزُّمَرِ
Surah Az-Zumar·39:58
أَوْ تَقُولَ حِينَ تَرَى الْعَذَابَ لَوْ أَنَّ لِي كَرَّةً فَأَكُونَ مِنَ الْمُحْسِنِينَ٥٨
or lest he should say, when he becomes aware of the suffering [that awaits him], “Would that I had a second chance [in life], so that I could be among the doers of good!”
