﴿ فَكَيْفَ إِذَآ أَصَٰبَتْهُم مُّصِيبَةٌۢ بِمَا قَدَّمَتْ أَيْدِيهِمْ ثُمَّ جَآءُوكَ يَحْلِفُونَ بِٱللَّهِ إِنْ أَرَدْنَآ إِلَّآ إِحْسَٰنًۭا وَتَوْفِيقًا ﴾

“But how [will they fare] when calamity befalls them [on the Day of Judgment] because of what they have wrought in this world - whereupon they will come to thee, swearing by God, "Our aim was but to do good, and to bring about harmony"?”
