Dua when Visiting Deceased at Grave

اللهُمَّ عَبْدُك وابنُ أَمَتِكَ ، احْتَاجَ إلى رَحْمَتِكَ ، وأنْتَ غَنِيٌّ عَنْ عَذَابِهِ ، إنْ كَانَ مُحسنًا فَزِدْ فِي حَسناتِه ، وإنْ كَانَ مُسِيئًا فَتَجَاوزْ عَنْه

Allahum abduk Wa ibin Amatak, ahtaaja ilaa rahmatika wa inta Ghani aan athaabih, Inn Kanna muhsinan fazed fi Hasanatih, Wa in Kanna musiaan fatajawaz Anh

O’ Allah, Your servant and the son of your servant is in need of Your Mercy and Your are without need of his punishment. If he was righteous then increase his reward and if he was wicked then look over his sins.
