الاحزاب — Al-Ahzab Ayat 9
يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوا اذْكُرُوْا نِعْمَةَ اللّٰهِ عَلَيْكُمْ اِذْ جَاۤءَتْكُمْ جُنُوْدٌ فَاَرْسَلْنَا عَلَيْهِمْ رِيْحًا وَّجُنُوْدًا لَّمْ تَرَوْهَا ۗوَكَانَ اللّٰهُ بِمَا تَعْمَلُوْنَ بَصِيْرًاۚ
Yā ayyuhal-lażīna āmanużkurū ni‘matallāhi ‘alaikum iż jā'atkum junūdun fa'arsalnā ‘alaihim rīḥaw wa junūdal lam tarauhā, wa kānallāhu bimā ta‘malūna baṣīrā(n).
"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."
