Our business with Jews is "only through bombs and guns"

Nizar Rayan, Hamas religious and military leader:
"Regarding the Jews, our business with them is only through bombs and guns... the prophet [Muhammad] promised that we will fight you, with Allah's help, until the tree and stone say: "Oh Muslim, servant of Allah, there is a Jew behind me, come and kill him."
[Nizar Rayan was killed in Gaza war the day after he made this statement.]
