33:56
إِنَّ ٱللَّهَ وَمَلَـٰٓئِكَتَهُۥ يُصَلُّونَ عَلَى ٱلنَّبِىِّ ۚ يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ صَلُّوا۟ عَلَيْهِ وَسَلِّمُوا۟ تَسْلِيمًا
inna l-laha wamalāikatahu yuṣallūna ʿalā l-nabiyi yāayyuhā alladhīna āmanū ṣallū ʿalayhi wasallimū taslīman
God and His angels bless the Prophet- so, you who believe, bless him too and give him greetings of peace.
Allâh sends His Salât (Graces, Honours, Blessings, Mercy) on the Prophet (Muhammad صلى الله عليه وسلم), and also His angels (ask Allâh to bless and forgive him). O you who believe! Send your Salât on (ask Allâh to bless) him (Muhammad صلى الله عليه وسلم), and (you should) greet (salute) him with the Islâmic way of greeting (salutation i.e. As-Salâmu ‘Alaikum ).
