Here they warn the Israelis that any stone disturbed on al-Aqsa will be met with "heavy bloodshed"; they call for the Palestinian factions to unite against Israel; they call for the withdrawal from any peace initiatives with Israel; and they call for Muslims to revive the duty of jihad and prepare for victory against Israel.
In sum, this looks like no more or less than a call for war against Israel (translated from salahsoltan.com, 24 Nov 2011):
The International Union of Muslim Scholars Calls on All Muslims to Make Next Friday, 25-11-2011, Al-Aqsa Friday
24 November 2011, salahsoltan.com
The International Union of Muslim Scholars (IUMS) calls on all Muslims to make next Friday, 25 November 2011, al-Aqsa Friday, and to stand with it physically and spiritually, and to give the Zionists a stern warning against trying to destroy the al-Aqsa Mosque. (The IUMS) calls on the Arab and Islamic world to protect it. The IUMS continues to be deeply concerned for what is happening in all of the blessed land of Palestine, from the al-Aqsa Mosque and al-Quds (Jerusalem) to the West Bank and Gaza. (The IUMS is) especially (concerned about) Zionist attempts through all means available to target the al-Aqsa Mosque in order to demolish the Mughrabi Gate Bridge, which connects the Wailing Wall and the blessed al-Aqsa Mosque. This is in order to build an iron bridge to allow artillery, tanks, and soldiers into the courtyards of the al-Aqsa Mosque, and threaten the security of the mosque and of praying Muslims. This is part of a terrible Judaization scheme, which has grown to the point of 37 tunnels underneath the al-Aqsa Mosque at a depth of 90 meters, building 50,000 settlement units, and changing 200,000 Arab names into Hebrew names, as some authorities have frankly admitted.
Before this imminent danger and these repeated attacks, the IUMS calls for the following:
1 - The IUMS issues a stern warning to the Zionists against proceeding with this dangerous plan (attempting to demolish al-Aqsa), which would inflame the conflict in the region. Al-Aqsa is the first of the two qiblas (direction to which Muslims turn when praying), and the site where the Messenger (PBUH) ascended. The site is also considered sacred to our Christian brothers.
Our basis for this stern warning is the deep Islamic and Arab roots is the powerful sentiment of Muslims toward their blessed holy sites, in addition to the fact that the Arab revolutions have paved the way for unity in the Islamic Ummah, which contains more than 1 billion 700 thousand people. All of them are of one heart concerning al-Aqsa and al-Quds (Jerusalem). Let the Zionists know that every stone, even every atom of al-Aqsa (which is disturbed) will be met with heavy bloodshed.
2 - The IUMS calls on the leaders of the Arab and Islamic Ummah to bear their responsibility for every stone in the blessed al-Aqsa Mosque through the following measures:
A - Support the resistance with all available resources, which is the only option for ending the occupation and protecting the holy sites.
B - Withdraw from the Arab peace initiative with the Zionist enemy, which no longer serves any benefit.
C - Suspend all peace treaties and expel Zionist ambassadors which remain in the country.
3 - The IUMS calls on the Ummah and its intellectuals and their parties to make Friday, 25 November 2011, "Save al-Aqsa Friday" through Friday sermons, sit-ins, prayers, and peaceful demonstrations.
4 - The IUMS calls immediately for the union of the Palestinian resistance, to be one rank (Truly Allah loves those who fight in His Cause in battle array, as if they were a solid cemented structure.-Qur'an 61:4). (The IUMS) also calls on the entire Ummah to revive the duty of jihad in all its forms, and prepare for the hour of victory and the liberation of al-Aqsa, al-Quds (Jerusalem), and Palestine from the Zionist enemies. It is coming by the promise of Allah Almighty to the believers, saying, "And another (favour will He bestow,) which ye do love,- help from Allah and a speedy victory. So give the Glad Tidings to the Believers" (Qur'an 61:13); "And We gave (Clear) Warning to the Children of Israel in the Book, that twice would they do mischief on the earth and be elated with mighty arrogance (and twice would they be punished)! When the first of the warnings came to pass, We sent against you Our servants given to terrible warfare: They entered the very inmost parts of your homes; and it was a warning (completely) fulfilled." Allah has spoken the truth.
