False confidence in material power and strength

فَأَمَّا عَادٌ فَٱسْتَكْبَرُوا۟ فِى ٱلْأَرْضِ بِغَيْرِ ٱلْحَقِّ وَقَالُوا۟ مَنْ أَشَدُّ مِنَّا قُوَّةً ۖ أَوَلَمْ يَرَوْا۟ أَنَّ ٱللَّهَ ٱلَّذِى خَلَقَهُمْ هُوَ أَشَدُّ مِنْهُمْ قُوَّةً ۖ وَكَانُوا۟ بِـَٔايَـٰتِنَا يَجْحَدُونَ

As for ʿAad, they were arrogant upon the earth without right and said, "Who is greater than us in strength?" Did they not consider that Allāh who created them was greater than them in strength? But they were rejecting Our signs.
