O most merciful Jesus, lover of souls, I beseech Thee by the agony of Thy Most Sacred Heart and by the sorrows of Thine Immaculate Mother, wash clean in Thy Blood the sinners of the whole world who are now in their agony and who are to die this day (here I especially include all those who'll die a sudden, unprovided for, or violent death) Amen.

V. Heart of Jesus,who didst suffer death's agony.
R. Have mercy on the dying.
