﴿ وَتَرَكْنَا فِيهَآ ءَايَةًۭ لِّلَّذِينَ يَخَافُونَ ٱلْعَذَابَ ٱلْأَلِيمَ ﴾

“And so We left therein a message for those who fear the grievous suffering [which awaits all evildoers].”

(And We left behind therein) in the townships of Lot's folk (a portent) a sign and lesson (for those who fear a painful doom) in the Hereafter such that they do not emulate their abominable act.
