Till the time Islam was weak during the Meccan period and the initial Medinan period, Quranic verses taught peace and tolerance and justice. But as soon as Islam became stronger in the later Medinan period, then it started teaching violence, cruelty, coercion and intolerance.

Let us compare Quranic Verses during these 2 periods to see these double standards of Quran.

 

Meccan and Initial Medinan Period, when Islam was weak

Later Medinan Period, when Islam became stronger

1

For you is your religion, and for me is my religion." (109.6)

And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers. (3:85)

kill the polytheists wherever you find them and capture them and besiege them and sit in wait for them at every place of ambush.(9:5)

5

And had your Lord willed, those on earth would have believed - all of them entirely. Then, [O Muhammad], would you compel the people in order that they become believers?(10:99)

Those who believe, and those who follow the Jewish (scriptures), and the Christians and the Sabians,- any who believe in Allah and the Last Day, and work righteousness, shall have their reward with their Lord; on them shall be no fear, nor shall they grieve. (2:62)

The Jews say, "Ezra is the son of Allah "; and the Christians say, "The Messiah is the son of Allah." That is their statement from their mouths; they imitate the saying of those who disbelieved [before them]. May Allah destroy them; how are they deluded? (9:30)

Against them make ready your strength to the utmost of your power, including steeds of war, to strike terror into (the hearts of) the enemies (8.60)

 

Excuse from Islam Apologists: 

Islam apologist wrote:

The pagans and people of the Book were hostile to Mo and broke peace treaties, that's when the violent verses were revealed.

Answer:

False excuse. For example, what has the following to do with peace treaties?

(Earlier) For you is your religion, and for me is my religion." (109.6)

(Later) And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers. (3:85)

And the MOST BRUTAL Quranic Verses were revealed in Surah Tauba (Surah Nr. 9). It was the time when Muhammad had already captured Mecca and there was no one left to challenge his powers, but instead of going for peace, he went for the most brutal killings of the non-Muslims and ordered to kill them where ever they be found.

The verse surah 9:29 was revealed stopping any obligation he might have to any treaties to Jews and Christians. Notice the verse is talking about their beliefs that Muslims must fight them not the fact that they have broken treaties or attacking them in any way.

Qur’an 9:29—Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the Religion of Truth, from among the People of the Book, until they pay the Jizyah with willing submission, and feel themselves subdued.

Qur’an 9:30—The Jews call Uzair a son of God, and the Christians call Christ the son of God. That is a saying from their mouth; (In this) they but imitate what the Unbelievers of old used to say. Allah’s curse be on them: how they are deluded away from the Truth!
