وَيَوْمَ نَبْعَثُ مِن كُلِّ أُمَّةٍ شَهِيدًا ثُمَّ لَا يُؤْذَنُ لِلَّذِينَ كَفَرُوا وَلَا هُمْ يُسْتَعْتَبُونَ ٨٤

And the Day when We shall raise from every people (their Messenger as) a witness (to their deeds), then the disbelievers will not be accorded permission (to put forward any excuse), nor will they be asked (then) to turn to Allah in repentance. (16:84)
