“We cannot fool ourselves. There is an Islamic problem. Al-Qaeda, Hamas, Hezbollah, Islamic Jihad, ISIS, Boko Haram, all of them are killing by the name of Allah. They’re not killing by the name of Jesus. They’re not killing by the name of Jehovah. They’re not killing by the name of Mahavira, or the Buddha, or Lao Tzu,” said Mosab Hassan Yousef, the son of a religious leader of Hamas.
