The custodian of Al-Aqsa Mosque says the message of Quds Day is that the world's Muslims are responsible for the holy site, the navigator of the Muslims.

On the last Friday of the holy month of Ramadan, by the initiative of the Founder of the Islamic Republic of Iran, Imam Khomeini, people across the world show united support for the oppressed people of Palestine to be the voice of the voiceless people of Palestine.
Also, a senior leader of Palestine's Islamic Jihad Movement told IP the attacks on Al-Aqsa Mosque originated from some Arab states' betrayal of the Palestinian cause. 
The Israeli attacks on Al-Aqsa Mosque have escalated during the days leading to Quds Day, while some Arab states including the UAE and Saudi Arabia have kept their lips closed. 
The coming Friday, April 29, 2022, is Quds World Day.
