Does Islam Encourage Violence?

Here is what several passages from the Quran says:

You will find other hypocrites who wish to be safe from you as well as from their own people; but who would plunge into mischief whenever they get an opportunity. Therefore if they do not keep distance from you and neither offer you peace, nor cease their hostilities against you, you may seize them and kill them wherever you find them, against such people We give you absolute authority. (4.19)

Male or female, whoever is guilty of theft, cut off the hand (that was used in theft) of either of them as a punishment for their crime. This is exemplary punishment ordained by Allah. Allah is Mighty, Wise. (5.38)

The Jews say: "Uzair (Azra) is the son of Allah," and the Christians say: " Messiah (Christ) is the son of Allah." That is what they say with their mouths, imitating the sayings of the former unbelievers. May Allah destroy them! How perverted they are! (9.30)

The woman and the man guilty of adultery or fornication—flog each of them with hundred stripes: Let no compassion move you in their case, in a matter prescribed by God, if ye believe in God and the last day. (24.2)

Those who accuse a chaste woman of fornication and do not produce four witnesses to support their allegation, shall be flogged with eighty lashes and their testimony shall not be accepted ever after, for they are the ones who are wicked transgressors   - except those who repent thereafter and mend their conduct; for Allah is surely Forgiving, Merciful. (24.4)

Therefore, when you meet the unbelievers in the battlefield smite their necks and, when you have thoroughly subdued them, then take prisoners of war and bind them firmly. After the war lay down her burdens, then you have the choice whether you show them favor or accept ransom. Thus are you commanded. If Allah wanted, He Himself could have punished them; but He adopted this way so that He may test some of you by means of others. As for those who are slain in the cause of Allah, He will never let their deeds be lost. (47.4)

This was a question that CNN asked.
