Read these quotes from the Qur'an and see for yourself the violent nature of this religion, thus betraying its error. Please understand that not all factions of the Islamic religion condone violence. Some do and some do not. I just wish to point out to you the Qur'an statements that seem to encourage violence.
"But when the forbidden months are past, then fight and slay the
Pagans wherever ye find them, an seize them, beleaguer them, and lie in
wait for them in every stratagem (of war); but if they repent, and establish
regular prayers and practise regular charity, then open the way for them:
for Allah is Oft-forgiving, Most Merciful."
Qur’an 9:5
"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
"O ye who believe! take not the Jews and the Christians for your
friends and protectors: They are but friends and protectors to each other.
And he amongst you that turns to them (for friendship) is of them. Verily
Allah guideth not a people unjust." Qur’an 5:51
"O ye who believe! take not for friends and protectors those who take
your religion for a mockery or sport,- whether among those who received
the Scripture before you, or among those who reject Faith; but fear ye
Allah, if ye have faith (indeed)."
Qur’an 5:57
"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
"Those who reject (Truth), among the People of the Book and among the
Polytheists, will be in Hell-Fire, to dwell therein (for aye). They are
the worst of creatures."
Qur’an 98:6
"If any of your women are guilty of lewdness, Take the evidence of four
(Reliable) witnesses from amongst you against them; and if they testify,
confine them to houses until death do claim them, or Allah ordain for them
some (other) way."
Qur’an 4:15
