There are 124 verses that call for tolerance and patience that have been cancelled and replaced by one, single verse. This verse is called the Verse of the Sword:
"But when the forbidden months are past, then fight and slay the Pagans wherever ye find them, and seize them, beleaguer them, and lie in wait for them in every stratagem (of war)..." Surah 9:5
The religion of Islam arose where there was no external imposition of limits, and it developed a religious doctrine quite different from other religions we are familiar with. Islamic doctrines unapologetically advocate the use of force, warfare, deceit, fear, torture, and slaughter to bring the law of Allah to the world.
There are 527 verses of intolerance toward non-Muslims, and 109 verses specifically advocating violence towards non-Muslims. Not one of these verses has been abrogated.
The Koran itself tells the believer how to handle its own contradictions. It says if a revelation contradicts one that came before it, the newer one overwrites the older one. This is the principle known as "abrogation." The bad news for non-Muslims is that all the intolerant and violent passages abrogate the earlier tolerant and peaceful ones.
