The contrast between outward appearance and inner reality

لَوْ يَجِدُونَ مَلْجَـًٔا أَوْ مَغَـٰرَٰتٍ أَوْ مُدَّخَلًا لَّوَلَّوْا۟ إِلَيْهِ وَهُمْ يَجْمَحُونَ

If they could find a refuge or some caves or any place to enter [and hide], they would turn to it while they run heedlessly.

۞ وَإِذَا رَأَيْتَهُمْ تُعْجِبُكَ أَجْسَامُهُمْ ۖ وَإِن يَقُولُوا۟ تَسْمَعْ لِقَوْلِهِمْ ۖ كَأَنَّهُمْ خُشُبٌ مُّسَنَّدَةٌ ۖ يَحْسَبُونَ كُلَّ صَيْحَةٍ عَلَيْهِمْ ۚ هُمُ ٱلْعَدُوُّ فَٱحْذَرْهُمْ ۚ قَـٰتَلَهُمُ ٱللَّهُ ۖ أَنَّىٰ يُؤْفَكُونَ

And when you see them, their forms please you, and if they speak, you listen to their speech. [They are] as if they were pieces of wood propped up - they think that every shout is against them. They are the enemy, so beware of them. May Allāh destroy them; how are they deluded?
