اللَّهُمَّ إِنْ كَانَ مُحْسِنًا فَزِدْ فِي إِحْسَانِهِ وَإِنْ كَانَ مُسِيئًا فَتَجَاوَزْ عَنْ سَيِّئَاتِهِ
Allahumma in kana muhsinan fazid fi ihsanihi wa in kana musi'an fatajawaz 'an sayyi'atih
O Allah, if he was a doer of good, then increase his good deeds, and if he was a wrongdoer, then overlook his misdeeds.
A janazah du'a that covers both possibilities without judgment. You do not know the deceased's true state — only Allah does. If they were good, ask for more. If they were bad, ask for forgiveness. The beauty is in the humility: you do not declare them righteous or sinful. You present both scenarios and let Allah's knowledge and mercy determine the outcome.
