To be said in the presence of the dying person (or from any place)

O most merciful Heart of Jesus, I beg You to grant to (Name of the person) whom You love, to unite his/her to Yours as You suffered our agony in the garden. Wash away with Your most precious Blood all the sins he/she has committed and for which he/she fears there may still be guilt.

Make his/her sufferings meritorious unto salvation. He/she wishes to pray in this manner: O Almighty God, I give You my body and soul for time and eternity. Forgive me all the sins that I have ever committed. I am sorry, I love You, I believe that Your divine Son became man and died for my sins. I believe that there are three persons in one God, Father, Son and Holy Spirit. I trust in You Lord Jesus to Save me. I want Your blessed Mother, Mary to pray for me now and at the hour of my death. I ask the prayers of my guardian angel and saints, and especially of my patron saint. Lord Jesus, grant me eternal salvation that I may be with You forever in the eternal bliss of my heavenly home. Amen.

Say the powerful Chaplet of the Divine Mercy

Write this: before I come as the just Judge, I am coming first as the King of Mercy. Before the day of justice arrives, there will be given to people a sign in the heaven of this sort:

All light in the heaven will be extinguished, and there will be great darkness over the whole earth. Then the sign of the cross will be seen in the sky, and from the openings where the hand and the feet of Savior were nailed will come forth great lights which will light up the earth for a period of time. This will take place shortly before the last day.
