"What is the matter with you"
"O you who believe! what is the matter with you, that, when you are asked to go forth in the Cause of Allah, you cling heavily to the earth? Do you prefer the life of this world to the Hereafter? But little is the comfort of this life, as compared with the Hereafter. Unless you go forth, He will punish you with a grievous penalty, and put others in you place; but Him you would not harm in the least. For Allah has power over all things." [Qur'an 9:38-39]
From the Qur'an, but could easily been from the mouth of Abdel Aziz Rantisi as he sent his followers into Israel to kill random people. Good riddance to bad rubbish.
