Al-An'am 6:28

<h2>Wishes and Hopes Do Not Help One When He Sees the Torment</h2><p>Allah mentions the condition of the disbelievers when they are made to stand before the Fire on the Day of Resurrection and witness its chains and restraints, along with seeing the horrible, momentous conditions in the Fire with their own eyes. This is when the disbelievers will say, </p><div class="arabic uthmani">يلَيْتَنَا نُرَدُّ وَلاَ نُكَذِّبَ بِـَايَـتِ رَبِّنَا وَنَكُونَ مِنَ الْمُؤْمِنِينَ</div><p>("Would that we were but sent back (to the world)! Then we would not deny the Ayat of our Lord, and we would be of the believers!") They wish that they would be sent back to the life of the world so that they could perform righteous deeds, refrain from disbelieving in the Ayat of their Lord and be among the believers. Allah said, </p><div class="arabic uthmani">بَلْ بَدَا لَهُمْ مَّا كَانُواْ يُخْفُونَ مِن قَبْلُ</div><p>(Nay, what they had been concealing before has become manifest to them.) meaning, the disbelief, denial and rebellion that they used to hide in their hearts will then be uncovered, even though they will try to hide this fact in this life and the Hereafter. Earlier, Allah said, </p><div class="arabic uthmani">ثُمَّ لَمْ تَكُنْ فِتْنَتُهُمْ إِلاَّ أَن قَالُواْ وَاللَّهِ …

Nay, but that hath become clear unto them which before they used to hide. And if they were sent back they would return unto that which they are forbidden. Lo! they are liars.

Yea, in their own (eyes) will become manifest what before they concealed. But if they were returned, they would certainly relapse to the things they were forbidden, for they are indeed liars.

Nay, it has become manifest to them what they had been concealing before. But if they were returned (to the world), they would certainly revert to that which they were forbidden. And indeed they are liars.

What they used to conceal before will become clear to them. And even if they were sent back, they would revert to what they were forbidden. They are liars.
