اللَّهُمَّ اغْفِرْ لَهُ وَارْحَمْهُ وَأَدْخِلْهُ الْجَنَّةَ وَأَعِذْهُ مِنْ عَذَابِ الْقَبْرِ
Allahummaghfir lahu warhamhu wa adkhilhul-jannata wa a'idhhu min 'adhabil-qabr
O Allah, forgive him, have mercy on him, admit him to Paradise, and protect him from the punishment of the grave.
This concise du'a covers the essential requests for the deceased. The Prophet ﷺ said: "When a person dies, his deeds come to an end except for three: ongoing charity, beneficial knowledge, or a righteous child who prays for him" (Sahih Muslim 1631). Du'a for deceased parents is one of the greatest acts of birr (righteousness) a child can do.
