Here are more spiritually inspirational verses:
Quran 8:12 Your Lord inspired the angels with the message: I will terrorize the unbelievers. Therefore smite them on their necks and every joint and incapacitate them. Strike off their heads and cut off each of their fingers and toes.
Tabari VII:133/Ishaq:387 When Muhammad saw Hamzah he said, If Allah gives me victory over the Quraysh at any time, I shall mutilate thirty of their men! When the Muslims saw the rage of the Prophet they said, By Allah, if we are victorious over them, we shall mutilate them in a way which no Arab has ever mutilated anybody.
Tabari VIII:96 A raiding party led by Zayd set out against Umm in Ramadan. During it, Umm suffered a cruel death. Zyad tied her legs with rope and then tied her between two camels until they split her in two. She was a very old woman. Then they brought Umms daughter and Abdallah to the Messenger. Umms daughter belonged to Salamah who had captured her. Muhammad asked Salamah for her, and Salamah gave her to him.
The Bible is full of this stuff, and plenty of Crusades, Inquisitions and pogroms remind us that brutality and murder in the name of Christianity is in no short supply. Only willful ignorance could hold otherwise. Yet, Christianity is not a bloodthirsty religion. Allow me to suggest that the same is true of Islam. Selective quote picking from the Koran is pretty unconvincing in light of this reality.
