يَوْمَ تَجِدُ كُلُّ نَفْسٍۢ مَّا عَمِلَتْ مِنْ خَيْرٍۢ مُّحْضَرًۭا وَمَا عَمِلَتْ مِن سُوٓءٍۢ تَوَدُّ لَوْ أَنَّ بَيْنَهَا وَبَيْنَهُۥٓ أَمَدًۢا بَعِيدًۭا ۗ وَيُحَذِّرُكُمُ ٱللَّهُ نَفْسَهُۥ ۗ وَٱللَّهُ رَءُوفٌۢ بِٱلْعِبَادِ
On the Day when every soul will find itself confronted with all that it hath done of good and all that it hath done of evil (every soul) will long that there might be a mighty space of distance between it and that (evil). Allah biddeth you beware of Him. And Allah is Full of Pity for (His) bondmen.
Surah Aal-i-Imraan(3:30)
