﴿ فَعَصَوْا۟ رَسُولَ رَبِّهِمْ فَأَخَذَهُمْ أَخْذَةًۭ رَّابِيَةً ﴾

“and rebelled against their Sustainer's apostles: and so He took them to task with a punishing grasp exceedingly severe!”

Then they disobeyed the messenger of their Lord namely Lot and others so He seized them with a devastating blow one surpassing others in its severity.
