How Rachel’s Tomb was IslamicizedThe article has much more on the history of the site from the Middle Ages through the modern period.
Between 1993 and 1995, Palestinian groups committed terror and suicide attacks that killed 80 Israelis. In February 1996, the IDF feared that Rachel’s Tomb would furnish a convenient target for an attack of this sort, as it was situated on the main highway connecting Jerusalem and Hebron, with heavy Jewish and Arab traffic. Demonstrations of a nationalist Palestinian character erupted at Rachel’s Tomb as Muslims began to raise the argument that the site involved “Islamic soil.”
At the end of September 1996, the “Western Wall Tunnel Riots” broke out. After the attack on Joseph’s Tomb in Nablus and its fall to the Palestinians, hundreds of Arabs from Bethlehem and the Aida refugee camp attacked Rachel’s Tomb. They set on fire the scaffolding that was erected around the tomb as part of fortification work at the site and tried to break into the compound. Marching at their head was Muhammad Rashad al-Jabari, the governor of Bethlehem, an appointee of the Palestinian Authority. The IDF dispersed the demonstrators with gunfire and stun grenades. Scores were wounded, including Kifah Barakat, the commander of Force 17, the presidential guard of PA chairman Yasser Arafat.
With the outbreak of the second intifada in 2000, Palestinians again attacked Rachel’s Tomb, and for 41 days Jews were prevented from visiting the site due to shooting incidents.
The Muslims also escalated their rhetoric. They stopped calling the site “Rachel’s Dome,” as they had done for hundreds of years, and began calling it the Mosque of Bilal ibn Rabah. The Muslim religious authorities (Wakf) first began to employ this name in 1996, and it eventually took root in Palestinian national discourse.
Bilal ibn Rabah, an Ethiopian by origin, is known in Islamic history as a black slave who served the household of the prophet Muhammad as the person in charge of calling the Muslims to prayer five times a day – the first muezzin. Upon the death of Muhammad, he went to fight the wars of Islam in Syria, was killed there in 642 CE, and was buried in Damascus. The Palestinian Authority raised the argument that, according to Islamic tradition, the Islamic conquerors of the country called the mosque that was established at Rachel’s Tomb after Bilal ibn Rabah.
Yet the Palestinian argument ignores the presumptive ownership that the Jews acquired at the site for many hundreds of years and from the firmans that the Ottoman authorities issued awarding Rachel’s Tomb to the Jews at the beginning of the 19th century.
The Palestinian arguments ignore even the accepted Muslim tradition that venerates Rachel and identifies the site as her burial place. Prof. Yehoshua Porat termed the claim of a mosque at Rachel’s Tomb as mendacious. He noted that the place was known in Arabic as “Rachel’s Dome – a Jewish place of worship.”
For many years in official publications of Palestinian national bodies, there was no reference to any other name for the site, including in the Palestinian Lexicon issued by the Arab League and the PLO in 1984, or in the Al-mawsu’ah al-filastiniyah published in Italy by the Palestinian Encyclopedia organization after 1996.
It sounds as though UNESCO's use of the title "Bilal bin Rabah Mosque" is historically spurious.
