The Prince of Wales has critised the persecution of Christians in the Middle East and asked the Muslim leaders to stop the "indescribable tragedy" taking place in Syria and Iraq.
Instead of "remaining silent," he said that the leaders of all faiths must ask the followers to respect people of other religions.
Speaking through a recorded video broadcast at the House of Lords ahead of the release of a new report that claims that Christians are the "most persecuted religious minority" in the world.
The study titled "Religious Freedom in the World Report – 2014"' states that freedom of religion for Christian under 'grave' threat in Muslim nations.
Calling the expulsion of Christians, Muslims and Yazidis from towns and cities, "horrendous and heart-breaking events in Iraq and Syria," he said that such "mounting despair" has brought the subject of religious freedom and persecution to the forefront of world's news.
Charles added that religion is essential to "our future as a free society."
"Sadly, incidents of violence in Iraq and Syria are not isolated. They are found throughout some, though not all, of the Middle East; in some African nations; and in many countries across Asia."
He called it an "indescribable tragedy" that Christianity was in a grave threat where Christians have lived for 2,000 years, especially after having lived peacefully along with the Muslims for centuries.
Charles, who someday will be the King stated that "believers" play a "crucial role" in ensuring a free society in Britain and around the world. Quoting Pope Francis, Prince Charles said that dialogue with other faiths was not only crucial to peace in the world, but was also a "duty" of all Christians.
"My own Christian faith has enabled me to speak to and to listen to people from other traditions, including Islam," he added.
"It is essential that governments honour their duty to uphold the right of people to practise their faith. Article 18 of the Universal Declaration of Human Rights is clear in stating that this right includes the freedom to change one's religion or belief. Yet even in the West this right is often challenged.
"Sadly, in many other countries, an absence of freedom to determine one's own faith is woven into the laws and customs of the nation."
Christian Daily, citing the report by Aid to the Church in Need stated that 41% of the countries in the world are places where religious freedom is impaired, either "high or medium", or is in decline.
The others show that 18 percent were "of concern" and the remaining 41 percent included "no concerns".
The video in which Prince Charlest has made the speech is part of the charity drive to collect funds to conducting, the "largest drive to provide food, shelter, and education to the more than 120,000 displaced Iraqi Christians in the Kurdish region."
