"O Allah! Shower Thy blessings on Hazrat Muhammad ever and ever until Thy blessings are to be showered. Grant Thy bounty and mercy on Muhammad until Thy bounty is granted and mercy is showered. The most selected favours on the Spirit of Muhammad amongst all persons, on the name of Muhammad amongst all names, on the heart of Muhammad amongst all hearts. Thy most bountiful favours on the grave of Muhammad amongst all graves, on the tomb of Muhammad amongst all the bodies, on the clay of Muhammad (tomb) amongst all clays. May Allah shower His blessings on Muhammad the best of all that and on the descendants of Muhammad, on the Companions of Muhammad, on the friends of Muhammad, and on all his family members, O! Merciful Almighty Allah and Great Merciful".
This Salawat is usually recited in the graveyard while paying homage to the deceased. When it is recited, Allah showers His blessings on the deceased.

Even many auliyas have instructed to read this. Auliyas like Hazrat khwaja Abdul bhai qaseer (RA) ( Khaleefa-e-Hazrat Khwaja-e-Bangalore ) use to instruct many to read this darood in Qabrastaan. This is also known as Darood-e-Qabrastaan or Durood-e-Hazaari.
If this durood is recited once ( 1 time ) near newly deceased person, there will be no azaab to the person inside the grave because of the greatness of this durood shareef.
