The full name of the movement is Ḥarakat al-Taḥrīr al-Waṭanī l-Filasṭīnī, meaning the "Palestinian National Liberation Movement". From this was crafted the inverted and reverse acronym Fatḥ (generally rendered in English as Fatah), meaning "opening", "conquering", or "victory".[30] The word fatḥ is used in religious discourse to signify the Islamic expansion in the first centuries of Islamic history – as in Fatḥ al-Shām, the "conquering of the Levant". Fatḥ also has religious significance in that it is the name of the 48th sura (chapter) of the Quran which, according to major Muslim commentators, details the story of the Treaty of Hudaybiyyah. During the peaceful two years after the Hudaybiyyah treaty, many converted to Islam, increasing the strength of the Muslim side. It was the breach of this treaty by the Quraysh[31] that triggered the conquest of Mecca. This Islamic precedent was cited by Yasser Arafat as justification for his signing the Oslo Accords with Israel.[32][33]
