Just a couple of excerpts from the Koran and Islamic teachings.
Believers, take neither Jews nor Christians for your friends. They are friends with one another. Whoever of you seeks their friendship will become one of their number. Allah does not guide the wrongdoers. Sura 5:51
A different translation says
[5:51] O you who believe, do not take certain Jews and Christians as allies; these are allies of one another. Those among you who ally themselves with these belong with them. GOD does not guide the transgressors.
Prophet, make war on the unbelievers and the hypocrites and deal rigorously with them. Hell shall be their home: an evil fate. Sura 9:73
Again a different translation
[9:73] O you prophet, strive against the disbelievers and the hypocrites, and be stern in dealing with them. Their destiny is Hell; what a miserable abode!
Fight against such of those to whom the Scriptures were given as believe neither in Allah nor the Last Day, who do not forbid what Allah and His apostle have forbidden and do not embrace the true faith until they pay tribute out of hand and are utterly subdued. Sura 9:29
Alternate translation
[9:29] You shall fight back against those who do not believe in GOD, nor in the Last Day, nor do they prohibit what GOD and His messenger have prohibited, nor do they abide by the religion of truth - among those who received the scripture - until they pay the due tax, willingly or unwillingly.
Mohammed is Allah's apostle. Those who follow him are ruthless to the unbelievers but merciful to one another. Sura 48:29
Aldernate translation
[48:29] Muhammad - the messenger of GOD - and those with him are harsh and stern against the disbelievers, but kind and compassionate amongst themselves. You see them bowing and prostrating, as they seek GOD's blessings and approval. Their marks are on their faces, because of prostrating. This is the same example as in the Torah. Their example in the Gospel is like plants that grow taller and stronger, and please the farmers. He thus enrages the disbelievers. GOD promises those among them who believe, and lead a righteous life, forgiveness and a great recompense.
The Hadith(Muslim oral tradition) states:]
"The Day of Resurrection will not arrive until the Muslims make war against the Jews and kill them, and until a Jew hiding behind a rock and tree, and the rock and tree will say: 'Oh Muslim, Oh servant of Allah, there is a Jew behind me, come and kill him!'"
