9:26
ثُمَّ أَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَنزَلَ جُنُودًا لَّمْ تَرَوْهَا وَعَذَّبَ ٱلَّذِينَ كَفَرُوا۟ ۚ وَذَٰلِكَ جَزَآءُ ٱلْكَـٰفِرِينَ
9:26
Then God sent down a sense of tranquility on His Apostle and the faithful; and sent down troops invisible to punish the infidels. This is the recompense of those who do not believe. - Ahmed Ali (English)
