Question
How is it to say RIP to a Non-Muslim who has died?
Answer
RIP (Rest in peace) is a sentence of Du’a, which gives the meaning of forgiveness for the dead. And Scholars have declared that making du’a of forgiveness for a non Muslim who has died is kufr.
Therefore, saying RIP is impermissible.
