﴿ وَلَوْ أَنَّآ أَهْلَكْنَٰهُم بِعَذَابٍۢ مِّن قَبْلِهِۦ لَقَالُوا۟ رَبَّنَا لَوْلَآ أَرْسَلْتَ إِلَيْنَا رَسُولًۭا فَنَتَّبِعَ ءَايَٰتِكَ مِن قَبْلِ أَن نَّذِلَّ وَنَخْزَىٰ ﴾

“For [thus it is:] had We destroyed them by means of a chastisement ere this [divine writ was revealed], they would indeed [be justified to] say [on Judgment Day]: "O our Sustainer! If only Thou hadst sent an apostle unto us, we would have followed Thy messages rather than be humiliated and disgraced [in the hereafter]!"”
