Tafsir of Al-Mutaffifeen 83:31

And when they returned to their own people, they would return jesting. meaning, when these criminals turn back, or return to their homes, they go back pleased. This means that whatever they request, they find it. Yet, with this, they still are not grateful for Allah's favor upon them. Rather they busy themselves with despising and envying the believers

وإذا رأوهم قالوا إن هوﻻإء لضالون
