فَكَيْفَ إِذَا جَمَعْنَٰهُمْ لِيَوْمٍۢ لَّا رَيْبَ فِيهِ وَوُفِّيَتْ كُلُّ نَفْسٍۢ مَّا كَسَبَتْ وَهُمْ لَا يُظْلَمُونَ
How (will it be with them) when We have brought them all together to a Day of which there is no doubt, when every soul will be paid in full what it hath earned, and they will not be wronged.
