﴿ مَآ ءَامَنَتْ قَبْلَهُم مِّن قَرْيَةٍ أَهْلَكْنَٰهَآ ۖ أَفَهُمْ يُؤْمِنُونَ ﴾

“Not one of the communities that We destroyed in bygone times would ever believe [their prophets]: will these, then, [be more willing to] believe?”

Then in اَفَھُم یؤمِنُونَ (Will they believe?) there is a hint that there was no likelihood of these people accepting the true faith even after seeing the miracles of their choice. Hence they were not shown the desired miracle.
