By Allah you will pay a high price, and what you are witnessing today is nothing but the beginning of the end of your empty kingdom. This is a small portion from your heavy bill that awaits you O Jews and Crusaders. Behold and wait, for we have come to you with men who love death the same way you love life, and whose drink is blood and their companions are body parts. They promised Allah that they will tear you to pieces and draw closer to Him in earnest by beheading you, dispersing your shredded bodies, and crushing your skulls. Indeed, the blood of the Muslims that was shed will not go in vain. You are striking us from the air by your planes and dropping the lava of your missiles, cruise rockets, and poisonous bombs over us, and we are striking your homes with our terror and responding to you with our hell and we will destroy you, kill you, and shake the earth beneath your feet inside your own homes. And by He who lifted the skies without pillars, you will never dream of safety until we are living it in realty in Palestine.

The news is what you see and not what you hear.

The grandchildren of Khaled are coming O Jews, so hold on to your necks, prepare your funeral shrouds, write your wills, and say goodbye to your families, for the battle has yet to begin.

I swear to you by Allah, not a night should pass, but your swords are dropping with kafir blood. Trust Allah, that every drop of blood shed there relieves the pressure on us here.

By Allah, my brothers, support the religion of Allah! By Allah, He will ask you about every Muslim woman, every killed child, woman, and old man. Allah will ask you about the blood, wealth, and honor of Muslims. Move suddenly, by Allah! Move suddenly, by Allah! Move suddenly, by Allah!
