9:26
ثُمَّ أَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَنزَلَ جُنُودًا لَّمْ تَرَوْهَا وَعَذَّبَ ٱلَّذِينَ كَفَرُوا۟ ۚ وَذَٰلِكَ جَزَآءُ ٱلْكَـٰفِرِينَ
9:26
Then Allah did send down His Sakinah (calmness, tranquillity and reassurance, etc.) on the Messenger (Muhammad SAW), and on the believers, and sent down forces (angels) which you saw not, and punished the disbelievers. Such is the recompense of disbelievers. - Muhammad Taqi-ud-Din al-Hilali and Muhammad Muhsin Khan (English)
