“ Allah and His Angels send blessings on the Prophet, O you who believe! send your blessings on him, and solute him a thorough salutation”. (33:56) One of the best ways to know the personality of great men is to study their literature and listen to their words. As Imam Ali states in Nahjul-Balagha : "Man is hidden behind his tongue” meaning by our words we introduce ourselves not with our certificates.

“ Allah and His Angels send Salat on the Prophet, O you who believe! send Salat on him, and solute him a thorough salutation”. (33:56)

As far as I know sending Salam and Salawat to the prophet of Islam, is one of the distinguishing characteristics of our Prophet, of which the previous prophets were deprived. Muslims across the world from the time the above Aya has been revealed up to the Day of Great Judgment are bound to send their Salawat onto the Prophet of Islam. Muslims five times a day when they call for Adhan and Eqama and even in their daily Prayers send their Salawat onto the Prophet of Islam.
therefore, the Salawat of Allah to the Prophet since it comes from Allah the Omnipotent, He is sending the constant blessings to His Messenger and hence, the Prophet becomes ‘ Rahmatun-lelalamin' (blessing for the universe). As, the Salawat of people to the Prophet is to pray to God to send His blessings to them through the Prophet who is Rahmatun-Lelalamin.

Allahumma Salli A'la Muhammad wa Aali Muhammad that means: Oh Allah, Grant Peace & Blessings to Prophet Muhammad & His Family
