calamity as consequence of deeds

فَكَيْفَ إِذَآ أَصَـٰبَتْهُم مُّصِيبَةٌۢ بِمَا قَدَّمَتْ أَيْدِيهِمْ ثُمَّ جَآءُوكَ يَحْلِفُونَ بِٱللَّهِ إِنْ أَرَدْنَآ إِلَّآ إِحْسَـٰنًا وَتَوْفِيقًا

So how [will it be] when disaster strikes them because of what their hands have put forth and then they come to you swearing by Allāh, "We intended nothing but good conduct and accommodation."
