Ayatollah Khomeini declared the last Friday of Ramadan as the International Day of Quds

Ayatollah Khomeini believed in the global spread of his revolution as well as Muslim brotherhood and cooperation. He held that one of the main objectives of the revolution should be to build an Islamic state all over the world, which should be done in cooperation with the far larger number of Sunni Muslims. The week between the 12th and the 17th of Rabi' al-Awwal was designated as Unity Week, commemorating the birth of Muhammad. In 1981, Ayatollah Khomeini declared the last Friday of the holy month of Ramadan as the International Day of Quds and urged the Muslim world to demonstrate solidarity with the oppressed people of Palestine and to protect their rights a few months after the revolution's triumph in the month of Ramadan 1399 ie August 1979.

Since then, large-scale protests and rallies are organized on this day in Iran and other nations to demonstrate sympathy for Palestinians. International Day of Quds is celebrated on this day every year that is dedicated to commemorating the ideals of truth, justice, and victory for the oppressed and tyrannized, three of the most essential concerns that are of great significance to the broader Islamic world as well as those who support and promote humanity.

For all Muslims, Quds day is a day of vigilance. They must remember this day. If every Muslim, every member of the Muslim country, participated in the demonstration and march on Quds Day on the final Friday of Ramadan, that would be the beginning of God's plan to halt the corrupt and drive them out of Muslim governments. Ayatollah Khomeini hopes that on the final Friday of the holy month of Ramadan, Muslims everywhere will celebrate Quds Day by organizing rallies, congregations, and demonstrations; assembling in mosques; and shouting slogans. Islam observes Quds Day as a day of universal Muslim mobilization. This is how Imam Khomeini emphasizes the importance and dimensions of Muslims across the world, including Muslims and non-Muslims, renewing the International Day of Quds.
