Quran 9:26 from Surah At-Tawba on Divine Marvels.
ثُمَّ أَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلۡمُؤۡمِنِينَ وَأَنزَلَ جُنُودٗا لَّمۡ تَرَوۡهَا وَعَذَّبَ ٱلَّذِينَ كَفَرُواْۚ وَذَٰلِكَ جَزَآءُ ٱلۡكَٰفِرِينَ
English translation: Then Allah sent down Allah sent down His tranquility on His Messenger and on the believers and sent down forces which you did not see which you did not see and He punished those who disbelieved And that (is) the recompense (of) the disbelievers
Transliteration: thumma anzala al-lahu sakinatahu ala rasulihi wa'ala al-mu'minina wa-anzala junudan lam tarawha wa'adhaba alladhina kafaru wadhalika jazau al-kafirina
