Surah Al-An'am, ayah 27

6:27

وَلَوۡ تَرَىٰٓ إِذۡ وُقِفُواْ عَلَى ٱلنَّارِ فَقَالُواْ يَٰلَيۡتَنَا نُرَدُّ وَلَا نُكَذِّبَ بِـَٔايَٰتِ رَبِّنَا وَنَكُونَ مِنَ ٱلۡمُؤۡمِنِينَ ٢٧

Walaw tarā idh wuqifū 'alan-nāri faqālū yālaytanā nuraddu walā nukaddhiba bi'āyāti rabbinā wanakūna minal-mu'minīn

If you could but see when they are made to stand before the Fire and will say, "Oh, would that we could be returned [to life on earth] and not deny the signs of our Lord and be among the believers."
