Verse 26

ثُمَّ أَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَنزَلَ جُنُودًا لَّمْ تَرَوْهَا وَعَذَّبَ ٱلَّذِينَ كَفَرُوا۟ وَذَٰلِكَ جَزَآءُ ٱلْكَـٰفِرِينَ

Afterwards, God sent down peaceful slumber upon His messenger and upon the faithful and sent down invisible armies and punished the unfaithful. And such is the requital for the unfaithful.
