Abrogation had a significant impact on the Quran, and is one of the primary reasons the traditional order of the Quran (with chapters arranged from the longest to the shortest chapter) so effectively prevents anyone who doesn't know about abrogation from understanding what it really says.
Only 43 chapters are not affected by abrogation.
This means most of the chapters of the Quran cannot be taken at face value.
Chapter 9:
9:5 Slay the idolaters wherever you find them.
9:6 Those who submit and convert to Islam will be treated well. (Those who don't submit will be killed. See previous verse.)
9:7-9 Don't make treaties with non-Muslims. They are all evildoers and should not be trusted.
9:11 Treat converts to Islam well, but kill those who refuse to convert (see 9:5).
9:12-14 Fight the disbelievers! Allah is on your side; he will give you victory.
9:23 Don't make friends with your disbelieving family members. Those who do so are wrong-doers.
9:29 Fight against Christians and Jews "until they pay the tribute readily, being brought low."
9:33 The "Religion of Truth" (Islam) must prevail, by force if necessary, over all other religions.
9:41 Fight for Allah with your wealth and whatever weapons are available to you.
9:42 Those who refuse to fight for Allah (claiming they are unable) are liars who have destroyed their souls.
9:73 Fight the disbelievers and hypocrites. Be harsh with them. They are all going to hell anyway.
9:81-83 Those who refuse to give their wealth and lives to Allah will face the fire of hell.
9:85 Those who refuse to fight for Allah will be treated (along with their children) as unbelievers.
9:111 Believers must fight for Allah. They must kill and be killed. Allah will reward them for it.
9:123 Fight disbelievers who are near you, and let them see the harshness in you.
This is Allah's "last word" on tolerance and peace toward non-Muslims.
It is at this point the tolerant verses are abrogated, the verses above makes null an void every last positive verse in the Quran for non-Muslims.
Muslims think itis OK to lie to the Kafir as long as it advances Islam.
This is the nature of Taqiyya
