Yellowtail: You ask for a referance, here it is, and some say this is a peaceful religion:
Qur’an 9:5 “Fight and kill the disbelievers wherever you find them, take them captive, harass them, lie in wait and ambush them using every stratagem of war.”
Qur’an 8:39 “So fight them until there is no more Fitnah (disbelief [non-Muslims]) and all submit to the religion of Allah alone (in the whole world).”
Ishaq:587 “Our onslaught will not be a weak faltering affair. We shall fight as long as we live. We will fight until you turn to Islam, humbly seeking refuge. We will fight not caring whom we meet. We will fight whether we destroy ancient holdings or newly gotten gains. We have mutilated every opponent. We have driven them violently before us at the command of Allah and Islam. We will fight until our religion is established. And we will plunder them, for they must suffer disgrace.”
Qur’an 3:146 “How many prophets fought in Allah’s Cause? With them (fought) myriads of godly men who were slain. They never lost heart if they met with disaster in Allah’s Cause, nor did they weaken nor give in. Allah loves those who are firm and steadfast [warriors].”
Qur’an 4:76 “Those who believe fight in the Cause of Allah.”
Qur’an 8:65 “O Prophet, urge the faithful to fight. If there are twenty among you with determination they will vanquish two hundred; if there are a hundred then they will slaughter a thousand unbelievers, for the infidels are a people devoid of understanding.”
Muslim:C34B20N4668 “The Messenger said: ‘Anybody who equips a warrior going to fight in the Way of Allah is like one who actually fights. And anybody who looks after his family in his absence is also like one who actually fights.”
Qur’an 47:4 “When you clash with the unbelieving Infidels in battle (fighting Jihad in Allah’s Cause), smite their necks until you overpower them, killing and wounding many of them. At length, when you have thoroughly subdued them, bind them firmly, making (them) captives. Thereafter either generosity or ransom (them based upon what benefits Islam) until the war lays down its burdens. Thus are you commanded by Allah to continue carrying out Jihad against the unbelieving infidels until they submit to Islam.”
Qur’an 9:19 “Do you make the giving of drink to pilgrims, or the maintenance of the Mosque, equal to those who fight in the Cause of Allah? They are not comparable in the sight of Allah. Those who believe, and left their homes, striving with might, fighting in Allah’s Cause with their goods and their lives, have the highest rank in the sight of Allah.”
Qur’an 2:193 “Fight them until there is no more Fitnah (disbelief) and religion is only for Allah. But if they cease/desist, let there be no hostility except against infidel disbelievers.”
Qur’an 2:244 “Fight in Allah’s Cause, and know that Allah hears and knows all.”
Muslim:C34B20N4668 and Ishaq is two of their (Muslim) holy scriptures.
