Surah At-Tawbah · Ayah 26

ثُمَّ أَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَنزَلَ جُنُودًۭا لَّمْ تَرَوْهَا وَعَذَّبَ ٱلَّذِينَ كَفَرُوا۟ ۚ وَذَٰلِكَ جَزَآءُ ٱلْكَٰفِرِينَ

Summa anzalal laahu sakeenatahoo 'alaa Rasoolihee wa 'alalmu 'mineena wa anzala junoodal lam tarawhaa wa azzabal lazeena kafaroo; wa zaalika jazaaa'ul kaafireen

Then Allah sent down His tranquillity upon His Messenger and upon the believers and sent down soldiers angels whom you did not see and punished those who disbelieved. And that is the recompense of the disbelievers.
