Quran (8:67) - "It is not for a Prophet that he should have prisoners of war until he had made a great slaughter in the land..."
Quran (8:59-60) - "And let not those who disbelieve suppose that they can outstrip (Allah's Purpose). Lo! they cannot escape. Make ready for them all thou canst of (armed) force and of horses tethered, that thereby ye may dismay the enemy of Allah and your enemy." As Ibn Kathir puts it in his tafsir on this passage, "Allah commands Muslims to prepare for war against disbelievers, as much as possible, according to affordability and availability."

Quran (8:65) - "O Prophet, exhort the believers to fight..."
Quran (9:5) - "So when the sacred months have passed away, then slay the idolaters wherever you find them, and take them captive and besiege them and lie in wait for them in every ambush, then if they repent and keep up prayer and pay the poor-rate, leave their way free to them." According to this verse, the best way of staying safe from Muslim violence at the time of Muhammad was to convert to Islam: prayer (salat) and the poor tax (zakat) are among the religion's Five Pillars. The popular claim that the Quran only inspires violence within the context of self-defense is seriously challenged by this passage as well, since the Muslims to whom it was written were obviously not under attack. Had they been, then there would have been no waiting period (earlier verses make it a duty for Muslims to fight in self-defense, even during the sacred months). The historical context is Mecca after the idolaters were subjugated by Muhammad and posed no threat. Once the Muslims had power, they violently evicted those unbelievers who would not convert.
