5:33 - "The punishment of those who wage war against Allah and His messenger and strive to make mischief in the land is only this, that they should be murdered or crucified or their hands and their feet should be cut off on opposite sides..."
8:12 - "Remember thy Lord inspired the angels (with the message): "I am with you: give firmness to the Believers: I will instill terror into the hearts of the Unbelievers: smite ye above their necks and smite all their fingertips off them."
And then there is this wonderful bit from the Hadith:
Ibn Ishaq 764 - After amassing a powerful army, Muhammad sent his forces to take the peaceful farming community of Khaybar by surprise. In the aftermath, he was dissatisfied with the amount of plunder and felt that the town’s treasurer, Kinana, might be holding out on him. He had the man brought to him:
When he [Muhammad] asked him about the rest he refused to produce it, so the apostle gave orders to al-Zubayr bin al-Awwam, “Torture him until you extract what he has.” So he kindled a fire with flint and steel on his chest until he was nearly dead. Then the apostle delivered him to Muhammad bin Maslama and he struck off his head.”
Maybe something was just lost in translation because Islam is the religion of peace.
Splendid idea!
