Quran 9:26 At-Tawbah, ayah 26 of 129

ثُمَّ أَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَنزَلَ جُنُودًا لَّمْ تَرَوْهَا وَعَذَّبَ ٱلَّذِينَ كَفَرُوا۟ ۚ وَذَٰلِكَ جَزَآءُ ٱلْكَـٰفِرِينَ ۝٢٦

9:26 Then Allah sent His peace of reassurance down upon His messenger and upon the believers, and sent down hosts ye could not see, and punished those who disbelieved. Such is the reward of disbelievers.
