Definition of Hamas as set out in their 1988 doctrine.
This they suffer, because they disbelieved the signs of Allah, and slew the prophets unjustly; this, because they were rebellious, and transgressed." (Al-Imran - verses 109-111).
Israel will exist and will continue to exist until Islam will obliterate it, just as it obliterated others before it" (The Martyr, Imam Hassan al-Banna, of blessed memory).
Our struggle against the Jews is very great and very serious. It needs all sincere efforts. It is a step that inevitably should be followed by other steps. The Movement is but one squadron that should be supported by more and more squadrons from this vast Arab and Islamic world, until the enemy is vanquished and Allah's victory is realised.
The Day of Judgement will not come about until Moslems fight the Jews (killing the Jews), when the Jew will hide behind stones and trees. The stones and trees will say O Moslems, O Abdulla, there is a Jew behind me, come and kill him. Only the Gharkad tree, (evidently a certain kind of tree) would not do that because it is one of the trees of the Jews." (related by al-Bukhari and Moslem).
But the Jews will not be pleased with thee, neither the Christians, until thou follow their religion; say, The direction of Allah is the true direction. And verily if thou follow their desires, after the knowledge which hath been given thee, thou shalt find no patron or protector against Allah." (The Cow - verse 120).
The day that enemies usurp part of Moslem land, Jihad becomes the individual duty of every Moslem. In face of the Jews' usurpation of Palestine, it is compulsory that the banner of Jihad be raised.
It is necessary to instill in the minds of the Moslem generations that the Palestinian problem is a religious problem, and should be dealt with on this basis. Palestine contains Islamic holy sites.
