وَلَوْ تَرَىٰٓ إِذْ وُقِفُوا۟ عَلَى ٱلنَّارِ فَقَالُوا۟ يَٰلَيْتَنَا نُرَدُّ وَلَا نُكَذِّبَ بِـَٔايَٰتِ رَبِّنَا وَنَكُونَ مِنَ ٱلْمُؤْمِنِينَ
If thou couldst see when they are set before the Fire and say: Oh, would that we might return! Then would we not deny the revelations of our Lord but we would be of the believers!
Surah Al-An'aam(6:27)
