"Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the religion of Truth, (even if they are) of the People of the Book, until they pay the Jizya with willing submission, and feel themselves subdued." -- Qur'an 9:29
Muslim spokesmen in the West routinely claim that this verse has no applicability in the modern world. They're lying.
"Syrian Jihadist Group Threatens United States," from IPT News, December 27:
A Syrian opposition group tied to al-Qaida has issued a threatening statement against the United States two weeks after the U.S. Treasury Department designated its leaders as terrorists.
A statement published on a jihadist website from Abu Mohammad Tahawi, a leading Jordanian Salafi jihadist who often trumpets the Nusrah Front in Syria, taunts the United States and President Obama and promises bloodshed.
The Nusrah Front "placed you long ago on the terrorism blacklist based on injustice, tyranny and vanquishing people," Tahawi wrote. "They have made a pledge for themselves to obey the oath of Sheikh Osama [bin Laden] … and you will not know a pleasant life, nor quiet and happy sleep until you return to your homes, with bowed heads, weary, miserable; and you pay them the Jizya (tax on non-Muslims), and are humbled ."
