The ruling on saying "the one whom Allah has forgiven" for a deceased person

Question:
May Allah reward you. This questioner asks: What is the ruling on saying "the one whom Allah has forgiven" for a dead person?

Answer:
No, this is a definitive statement, and one does not make a definitive statement of forgiveness and mercy for anyone. Rather, one supplicates for his forgiveness, except for those about whom the Messenger (peace and blessings be upon him) or the Qur'an has informed that Allah has forgiven them; for these, one may make a definitive statement of forgiveness. As for others, forgiveness is hoped for them, and one supplicates for their forgiveness.
