"The Western dogs are rejoicing after killing one of our Islamic lions. From al-Aqsa Mosque, where the future caliphate will originate with the help of God, we say to them -- the dogs will not rejoice too much for killing the lions. The dogs will remain dogs and the lion, even if he is dead, will remain a lion." -- Imam at the al-Aqsa Mosque in Jerusalem, YouTube, May 2, 2011.
