Verse 39

إِلَّا تَنفِرُوا۟ يُعَذِّبْكُمْ عَذَابًا أَلِيمًا وَيَسْتَبْدِلْ قَوْمًا غَيْرَكُمْ وَلَا تَضُرُّوهُ شَيْـًٔا وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ

Unless you mobilize, He will make you suffer, a most painful suffering and will replace you with other people, and nothing will harm Him. And God is All Powerful over all things.
