بِسْمِ اللهِ الرَّحْمٰنِ الرَّحِيْمِ
السلام علیکم ورحمۃ الله وبرکاتہ
The Prophet ﷺ also urged us to do that and explained that it brings a multiple reward and that it is a means of attaining forgiveness of sins and having one’s needs met. He ﷺ said:Sending blessings upon the Prophet ﷺ is one of the greatest acts of worship encouraged in Islam, and it is one of the most beneficial supplications for a person in this world and the hereafter, and it is one of the requirements of loving, venerating and respecting the Prophet ﷺ and giving him his rights. Allah, may He be exalted, says (interpretation of the meaning):
“Allah sends His Salât (Graces, Honours, Blessings, Mercy) on the Prophet and also His angels (ask Allah to bless and forgive him). O you who believe! Send your Salât on (ask Allah to bless him), and (you should) greet (salute) him with the Islamic way of greeting (salutation i.e. As¬Salâmu 'Alaikum)”
[Al-Ahzaab 33:56]
The virtue of sending blessings upon the Prophet ﷺ does not benefit the Prophet ﷺ only; rather it also benefits the one who sends blessings on him. The virtue mentioned in the hadiths quoted above and in other hadiths benefits the one who sends blessings upon the Prophet ﷺ.“Whoever sends blessings upon me once, Allah will send blessings upon him tenfold and will erase from him ten misdeeds and raise him ten degrees in status.”
