ثُمَّ أَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَنزَلَ جُنُودًا لَّمْ تَرَوْهَا وَعَذَّبَ ٱلَّذِينَ كَفَرُوا۟ ۚ وَذَٰلِكَ جَزَآءُ ٱلْكَـٰفِرِينَ
thumma anzala l-lahu sakīnatahu ʿalā rasūlihi waʿalā l-mu'minīna wa-anzala junūdan lam tarawhā waʿadhaba alladhīna kafarū wadhālika jazāu l-kāfirīna
Then God sent His calm down to His Messenger and the believers, and He sent down invisible forces. He punished the disbelievers- this is what the disbelievers deserve-
Then Allâh did send down His Sakînah (calmness, tranquillity and reassurance) on the Messenger (Muhammad صلى الله عليه وسلم), and on the believers, and sent down forces (angels) which you saw not, and punished the disbelievers. Such is the recompense of disbelievers.
