Indeed, Allah showers His blessings upon the Prophet, and His angels pray for him. O  believers! Invoke Allah’s blessings upon him, and salute him with worthy 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 Salât¹ 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 ).
