Sunan an-Nasa'i #1986 · The Book of Funerals

he heard the Prophet say, when offering the funeral prayer for one who had died: Allahummighfir lihayyina wa mayyitina wa shahidina wa gha'ibina wadhakarina wa unthana wa saghirina wa kabirina (O Allah, forgive our living and our dead, those who are present among us and those who are absent, our males and our females, our young and our old)
