Hmmm...I was kinda hoping for a one line verse from the Quoran rather than a novel about it. I've always found that the longer the explanation, the less likely it is true.
Maybe someone can point out a quick Quoran reference.
In the Hadith Volume 5, Book 59, Number 369, we see Mohamed make a specific provision for Muslims to lie if it will help them to kill an enemy.
Allah's Apostle said, "Who is willing to kill Ka'b bin Al-Ashraf who has hurt Allah and His Apostle?" Thereupon Muhammad bin Maslama got up saying, "O Allah's Apostle! Would you like that I kill him?" The Prophet said, "Yes," Muhammad bin Maslama said, "Then allow me to say a (false) thing (i.e. to deceive Kab). "The Prophet said, "You may say it."
Not from the Koran, but still islamic scripture.
