وَلَقَدْ أَتَوْا۟ عَلَى ٱلْقَرْيَةِ ٱلَّتِىٓ أُمْطِرَتْ مَطَرَ ٱلسَّوْءِ ۚ أَفَلَمْ يَكُونُوا۟ يَرَوْنَهَا ۚ بَلْ كَانُوا۟ لَا يَرْجُونَ نُشُورًۭا
And indeed they have passed by the township whereon was rained the fatal rain. Can it be that they have not seen it? Nay, but they hope for no resurrection.
