Jesus Revealed this powerful prayer to St. Faustina as one of the best means to assist the dying. Jesus said: “My daughter, encourage souls to say the chaplet which I have given to you. It pleases Me to grant everything they ask of Me by saying the chaplet...Write that when they say this chaplet in the presence of the dying person, not as the just Judge but as the merciful Savior” (Diary 1541) Earlier our Lord said to her: “At the hour of their death, I defend as My own glory every soul that will say this chaplet; or when others say it for the dying person, the indulgence is the same.” (Diary, 811) Jesus said: “When this chaplet is said by the bedside of the dying person, divine wrath is placated, unfathomable mercy envelopes the soul, and the very depths of My tender mercy are moved for the sake of the sorrowful Passion of My Son (Diary, 811)”. St. Faustina makes it clear in her diary that one does not need have to be at the bedside physically when praying the chaplet for the sick or dying person (Diary 835).
