Mujahid: Assalaam Alaykum, we are in the Holy Land. Allah be praised, we are in Syria. Today, we’re going to speak in Spanish. I have with me my brother. Go ahead, man.
Second mujahid: In the name of Allah, the Merciful, the Compassionate. Thanks be to Allah. Allah be praised, we are in the Holy Land, the land of Sham.
I say to the entire world as a warning: We are living under the Islamic banner, the Islamic Caliphate. We are going to die to it until we liberate all the occupied lands, from Jakarta to Andalusia, Allah willing.
I tell you, Spain is the land of our forefathers, and, Allah willing, we are going to liberate it, with the might of Allah.
