ignorance despite knowledge

قَالَ إِنَّمَآ أُوتِيتُهُۥ عَلَىٰ عِلْمٍ عِندِىٓ ۚ أَوَلَمْ يَعْلَمْ أَنَّ ٱللَّهَ قَدْ أَهْلَكَ مِن قَبْلِهِۦ مِنَ ٱلْقُرُونِ مَنْ هُوَ أَشَدُّ مِنْهُ قُوَّةً وَأَكْثَرُ جَمْعًا ۚ وَلَا يُسْـَٔلُ عَن ذُنُوبِهِمُ ٱلْمُجْرِمُونَ

He said, "I was only given it because of knowledge I have." Did he not know that Allāh had destroyed before him of generations those who were greater than him in power and greater in accumulation [of wealth]? But the criminals, about their sins, will not be asked.
