Abraham has been an important figure for theologians, philosophers, chroniclers and religious poets and lyricists among Jews, Christians and Muslims. All three monotheistic religions honor him and claim him as a patriarch or in Islam's case as a prophet of the one God. All tell the story of his willingness to sacrifice his son for God. Jews and Arabs see him as an ancestor, Jews claiming descent through his implausibly aged first wife Sarah and Arabs through his second wife (held in some Jewish and Muslim traditions to have been a Pharaonic princess), Hagar. They hold him to be buried in the Cave of the Patriarchs in al-Khalil in the Palestinian West Bank, which the Israelis call "Hebron," where Muslims erected the Mosque of the Abraham, which is split, with part of it used by Jews and the other part by Muslims.
(Update: Francis Boyle writes in to say: "The Muslims and the Jews do not “share” the Ibrahimi Mosque. In fact, Israel confiscated the chamber of the Mosque where Ibrahim, Isaac, Jacob and their wives are buried, then built a synagogue in there. In other words, the Israelis desecrated the Mosque by building a synagogue within it. I have seen it myself, truly disgusting. This regime is enforced by armed Israeli soldiers within the Mosque—further desecrating it. This was clearly a war crime in violation of the Fourth Geneva Convention, inter alia.")
Abraham is frequently cited as a figure who should unite Jews, Christians and Muslims, since all view him as the first monotheist and a founder figure for their traditions. But last week the Israeli government designated the Cave of the Patriarchs an Israeli heritage site. Since it is on the Palestinian West Bank, it cannot be an Israeli heritage site, though it certainly is a Jewish one.
Palestinians are afraid that Israeli Prime Minister Binyamin Netanyahu's action is a prelude to an Israeli claim on the annexation of al-Khalil to Israel. The town of 150,000 is completely made up of Palestinian Christians and Muslims, though 400 Israeli settlers, some of them armed and all under the protection of the Israeli military, reside there. There have been constant frictions between the small Israeli colony and the Palestinian townspeople.
