6:27
وَلَوْ تَرَىٰٓ إِذْ وُقِفُوا۟ عَلَى ٱلنَّارِ فَقَالُوا۟ يَـٰلَيْتَنَا نُرَدُّ وَلَا نُكَذِّبَ بِـَٔايَـٰتِ رَبِّنَا وَنَكُونَ مِنَ ٱلْمُؤْمِنِينَ
walaw tarā idh wuqifū ʿalā l-nāri faqālū yālaytanā nuraddu walā nukadhiba biāyāti rabbinā wanakūna mina l-mu'minīna
If you could only see, when they are made to stand before the Fire, how they will say, ‘If only we could be sent back, we would not reject the revelations of our Lord, but be among the believers.’
If you could but see when they will be held over the (Hell) Fire! They will say: "Would that we were but sent back (to the world)! Then we would not deny the Ayât (proofs, evidence, verses, lessons, revelations, etc.) of our Lord, and we would be of the believers!"
