Surah At-Tawba, Verse 26
ثُمَّ أَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَنزَلَ جُنُودًۭا لَّمْ تَرَوْهَا وَعَذَّبَ ٱلَّذِينَ كَفَرُوا۟ ۚ وَذَٰلِكَ جَزَآءُ ٱلْكَٰفِرِينَ
Translation — Sahih International
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.
