هَلْ يَنظُرُونَ إِلَّا تَأْوِيلَهُۥ ۚ يَوْمَ يَأْتِى تَأْوِيلُهُۥ يَقُولُ ٱلَّذِينَ نَسُوهُ مِن قَبْلُ قَدْ جَآءَتْ رُسُلُ رَبِّنَا بِٱلْحَقِّ فَهَل لَّنَا مِن شُفَعَآءَ فَيَشْفَعُوا۟ لَنَآ أَوْ نُرَدُّ فَنَعْمَلَ غَيْرَ ٱلَّذِى كُنَّا نَعْمَلُ ۚ قَدْ خَسِرُوٓا۟ أَنفُسَهُمْ وَضَلَّ عَنْهُم مَّا كَانُوا۟ يَفْتَرُونَ
Await they aught save the fulfilment thereof? On the day when the fulfilment thereof cometh, those who were before forgetful thereof will say: The messengers of our Lord did bring the Truth! Have we any intercessors, that they may intercede for us? Or can we be returned (to life on earth), that we may act otherwise than we used to act? They have lost their souls, and that which they devised hath failed them.
Surah Al-A'raaf(7:53)
