At-Taubah - 9:26

ثُمَّ أَنَزلَ اللّهُ سَكِينَتَهُ عَلَى رَسُولِهِ وَعَلَى الْمُؤْمِنِينَ وَأَنزَلَ جُنُودًا لَّمْ تَرَوْهَا وَعذَّبَ الَّذِينَ كَفَرُواْ وَذَلِكَ جَزَاء الْكَافِرِينَ
[9:26]
Then Allah sent down His tranquillity upon His Messenger and upon the believers, and sent down hosts which you did not see, and chastised those who disbelieved, and that is the reward of the unbelievers.
But Allah did pour His calm on the Messenger and on the Believers, and sent down forces which ye saw not: He punished the Unbelievers; thus doth He reward those without Faith.
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.
