Read Ruku 127 of the Quran

وَلَقَدْ جِئْنَـٰهُم بِكِتَـٰبٍۢ فَصَّلْنَـٰهُ عَلَىٰ عِلْمٍ هُدًۭى وَرَحْمَةًۭ لِّقَوْمٍۢ يُؤْمِنُونَ ﴿٥٢﴾

And We had certainly brought them a Book which We detailed by knowledge - as guidance and mercy to a people who believe.

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 ﴿٥٣﴾

Do they await except its result? The Day its result comes those who had ignored it before will say, "The messengers of our Lord had come with the truth, so are there [now] any intercessors to intercede for us or could we be sent back to do other than we used to do?" They will have lost themselves, and lost from them is what they used to invent.
