Hudna (هدنة) is an Arabic term meaning "truce" or "armistice" as well as "calm" or "quiet", coming from a verbal root meaning "calm". It is sometimes translated as "cease-fire". In the Lisan al-Arab (Ibn al-Manzur's definitive dictionary of classical Arabic, dating to the 14th century) it is defined as follows:
A particularly famous early hudna was the Treaty of Hudaybiyyah between Muhammad and the Quraysh tribe.
According to Umdat as-Salik, a medieval summary of Shafi'i jurisprudence, hudnas with a non-Muslim enemy should be limited to 10 years: "if Muslims are weak, a truce may be made for ten years if necessary, for the Prophet (Allah bless him and give him peace) made a truce with the Quraysh for that long, as is related by Abu Dawud" ('Umdat as-Salik, o9.16).
Despite the Israeli government's rejection of the idea, in summer 2003 — following pressure from Abu Mazen and Egypt — Hamas and Islamic Jihad unilaterally declared a 45-day ceasefire, or hudna. Its proponents commonly argued that such a cease-fire would allow hostility to die down and make a full reconciliation possible; its opponents commonly argued that it would be a mere tactical maneuver enabling Palestinian groups to re-group and muster their strength in preparation for further attacks on Israelis, or Israel to continue expanding settlements, blockading Palestinian towns, and arresting members of such groups*. The hudna started in late June 2003.
Israel — which had not made any agreement — continued to hunt down terrorist operatives, while Islamic Jihad and the Al-Aqsa Martyrs Brigade continued a series of attacks on Israeli citizens throughout the month of July. Hamas, claiming to have no involvement in the attacks, officially observed the hudna until, on August 8, the IDF killed two Hamas members, to which Hamas responded with a suicide bombing on August 12, killing one Israeli civilian. Fatah claimed responsibility for a second suicide bombing on August 12 killing another Israeli citizen. Despite this de facto violation of the hudna, Hamas stated that the cease-fire would continue. Hostilities then escalated: the Israeli army killed Islamic Jihad's Muhammad Seeder on August 14; the Jerusalem bus 2 massacre by Hamas and Islamic Jihad on August 19, killed 23 and wounded 136 people ; and Israeli forces killed Hamas's Isma'il Abu-Shanab on August 21. After the killing of the two high-ranking leaders, Hamas eventually called off the hudna*.
In January 2004, senior Hamas leader Abdel Aziz al-Rantissi offered a 10-year hudna in return for complete withdrawal from all territories captured in the Six Day War, and the establishment of a Palestinian state in the West Bank and Gaza. Rantissi said the hudna was limited to ten years and represented a decision by the movement because it was "difficult to liberate all our land at this stage; the hudna would however not signal a recognition of the state of Israel." Hamas' former spiritual leader Sheikh Ahmed Yassin made similar statements at this time, including a one hundred year Hudna. Israel characterised the offer as ridiculous and a "smoke screen for military preparations". Both Israel and the United States insist that Hamas is "an enemy of peace" that must be disarmed and dismantledFollowing further terror attacks by Hamas, Yassin was killed by Israel in March 2004, Rantissi in April[http://www.aljazeerah.info/News%20archives/2004%20News%20archives/Jan/27n/Hamas%20proposal%20of%2010year%20truce%20scorned.htm.
