Sura 16 Al-Nahl (The Bee), ayah 84

1. وَيَوْمَ نَبْعَثُ مِنْ كُلِّ أُمَّةٍ شَهِيدًا ثُمَّ لَا يُؤْذَنُ لِلَّذِينَ كَفَرُوا وَلَا هُمْ يُسْتَعْتَبُونَ

   And (mention) the Day when We will resurrect from every nation a witness. Then it will not be permitted to the disbelievers (to apologize or make excuses), nor will they be asked to appease (Allah).

   16:84
