ثُمَّ أَنزَلَ اللَّهُ سَكِينَتَهُ عَلَى رَسُولِهِ وَعَلَى الْمُؤْمِنِينَ وَأَنزَلَ جُنُودًا لَّمْ تَرَوْهَا وَعَذَّبَ الَّذِينَ كَفَرُوا وَذَلِكَ جَزَاءُ الْكَافِرِينَ

Then Allah sent down His composure upon His Apostle and upon the faithful, and He sent down hosts you did not see, and He punished the faithless, and that is the requital of the faithless.
