Can I pray for the forgiveness of a non-muslim
Answer
Wa’alayhum as Salam wa rahmallahi wa barakatuhu,
As long as a disbeliever is alive, you may pray for them. You can ask Allah to bless them with guidance, good health, protection etc.
However, once a person passes away as a disbeliever, it is not permissible to pray for his forgiveness. This is categorically prohibited in the Quran.
And Allaah Ta’aala knows best
Wassalaam,
