Our Lady in Medjugorje tells you which is the most beautiful prayer

Message dated February 18, 1983
The most beautiful prayer is the Creed. But all prayers are good and pleasing to God if they come from the heart.
Some passages from the Bible that can help us understand this message.
Tobias 12,8-12
Good thing is prayer with fasting and almsgiving with justice. Better the little with justice than wealth with injustice. It is better to give alms than to put aside gold. Begging saves from death and purifies from all sin. Those who give alms will enjoy long life. Those who commit sin and injustice are enemies of their lives. I want to show you the whole truth, without hiding anything: I have already taught you that it is good to hide the king's secret, while it is glorious to reveal the works of God. Know therefore that, when you and Sara were in prayer, I would present the witness of your prayer before the glory of the Lord. So even when you buried the dead.
Proverbs 15,25-33

Whoever is greedy for dishonest earnings upsets his home; but whoever detests gifts will live. The mind of the righteous meditates before answering, the mouth of the wicked expresses wickedness. The Lord is far from the wicked, but he listens to the prayers of the righteous. A luminous look gladdens the heart; happy news revives the bones. The ear that listens to a salutary rebuke will have its home in the midst of the wise. Whoever refuses the correction despises himself, who listens to the rebuke acquires sense. Fear of God is a school of wisdom, before glory there is humility.
Proverbs 28,1-10

For the crimes of a country many are his tyrants, but with an intelligent and wise man the order is maintained. An ungodly man who oppresses the poor is a torrential rain that does not bring bread. Those who violate the law praise the wicked, but those who observe the law wage war on him. The wicked do not understand justice, but those who seek the Lord understand everything. A poor man with an intact conduct is better than one with perverse customs, even if he is rich. He who observes the law is an intelligent son, who attends the crapulons dishonors his father. Whoever increases the patrimony with usury and interest accumulates it for those who have pity on the poor. Whoever turns his ear elsewhere so as not to listen to the law, even his prayer is abominable. Various maxims Whoever causes righteous men to be led astray by a bad path, will himself fall into the pit, while intact
