Surah Al-Ahzab, Verse 9

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ ٱذۡكُرُواْ نِعۡمَةَ ٱللَّهِ عَلَيۡكُمۡ إِذۡ جَآءَتۡكُمۡ جُنُودٞ فَأَرۡسَلۡنَا عَلَيۡهِمۡ رِيحٗا وَجُنُودٗا لَّمۡ تَرَوۡهَاۚ وَكَانَ ٱللَّهُ بِمَا تَعۡمَلُونَ بَصِيرًا٩

yāayyuhā alladhīna āmanū udh'kurū niʿ'mata l-lahi ʿalaykum idh jāatkum junūdun fa-arsalnā ʿalayhim rīḥan wajunūdan lam tarawhā wakāna l-lahu bimā taʿmalūna baṣīran

O you who have believed, remember the favor of Allāh upon you when armies came to [attack] you and We sent upon them a wind and armies [of angels] you did not see. And ever is Allāh, of what you do, Seeing.
