يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱذْكُرُوا۟ نِعْمَةَ ٱللَّهِ عَلَيْكُمْ إِذْ جَآءَتْكُمْ جُنُودٌۭ فَأَرْسَلْنَا عَلَيْهِمْ رِيحًۭا وَجُنُودًۭا لَّمْ تَرَوْهَا ۚ وَكَانَ ٱللَّهُ بِمَا تَعْمَلُونَ بَصِيرًا

O you who have believed, remember the favor of Allah 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 Allah, of what you do, Seeing.

— Al-Aḥzāb 33:9
