"Those who annoy Allah and His Messenger – Allah has cursed them in this World and in the Hereafter, and has prepared for them a humiliating Punishment. Truly, if the Hypocrites, and those in whose hearts is a disease, and those who stir up sedition in the City, desist not, We shall certainly stir thee up against them: Then will they not be able to stay in it as thy neighbours for any length of time: They shall have a curse on them: whenever they are found, they shall be seized and slain (without mercy)."
