The Virgin Mary told the three children of Fatima, Portugal, to pray the rosary daily for the conversion of sinners and for peace in the world. She also asked that the following prayer be said after each decade of the rosary.
Oh My Jesus, forgive us our sins, save us from the fires of Hell, lead all souls to Heaven, especially those in most need of Thy mercy.
“Remember when you leave this world you can take nothing of what you have received, but only what you have given: a full heart, enriched by honest service, love, sacrifice, and courage.” ―St. Francis of Assisi
The Transitus of St. Francis is commemorated on the evening of October 3rd, the vigil of his feast day. Please see the link below from the Franciscan Missionaries of the Eternal Word that provides excellent ways to honor the feast of St. Francis.
