'Jerusalem Day'), officially known as International Quds Day (Persian: روز جهانی قدس, romanized: Ruz Jahâni Quds), is an annual pro-Palestinian event held on the last Friday of the Islamic holy month of Ramadan to express support for Palestinians and oppose Israel and Zionism.

[13][14][15] An annual anti-Zionist day of protest was first suggested by Ebrahim Yazdi, the first foreign minister of the Islamic Republic of Iran, to Ruhollah Khomeini, the leader of the Iranian Revolution.

Khomeini adopted Yazdi's idea,[4] and on 7 August 1979, he declared the last Friday of every Ramadan as "Quds Day", in which Muslims worldwide would unite in solidarity against Israel and in support of the Palestinians.

I ask God Almighty for the victory of the Muslims over the infidels.There have been recorded incidents of violence on Quds Day, including 28 people killed and 326 wounded by bombs in 1985 during the Iran–Iraq War.

Arab societies generally pay the occasion lip service in order to make a show of solidarity with the cause of Palestinian aspirations for nationhood.

In January 1988, during the First Intifada, the Jerusalem Committee of the Organization of the Islamic Conference decided that Quds Day should be commemorated in public events throughout the Arab world.

[22] According to the BBC, while the original idea behind Quds Day was to gather all Muslims in opposition to the existence of Israel, the event has not developed beyond an Iranian experience.

[26][27][28] In 2020, for the first time since the initiation four decades ago, the Quds day event was held virtually in Iran amid the COVID-19 pandemic.
