Should I delete the photos and videos that I have with my deceased fiancé?

Digital images are not among the prohibited forms of photography, and there is no original prohibition against keeping them. However, in this case, if the images depict a forbidden relationship before marriage (a fiancé, not a husband), then they must be deleted, and one must repent from the sin they represent. This is more merciful to the deceased and more beneficial for him. Furthermore, looking at them renews sorrow and preoccupies the heart without benefit, so they ought to be deleted.
