Here is an example of a very misunderstood verse in the Quran...
Surah 14:4
And We never sent a messenger save with the language of his folk, that he might make (the message) clear for them. Then Allah sendeth whom He will astray, and guideth whom He will. He is the Mighty, the Wise.

People will tend to argue that Allah misguides people and therefore when the people are misguided then they don't have free will and that it is actually Allah's fault for them being misguided and that Allah would be unjust for punishing them.
However, lets read the Quran in con**** so that we can better understand what this verse is saying. I won't be using any commentaries because once someone reads the Quran in con**** he could easily understand what the verse is saying.

Surah 18:29
Say: (It is) the truth from the Lord of you (all). Then whosoever will, let him believe, and whosoever will, let him disbelieve. Lo! We have prepared for disbelievers Fire. Its tent encloseth them. If they ask for showers, they will be showered with water like to molten lead which burneth the faces. Calamitous the drink and ill the resting-place!
Here we clearly see that people have a FREE WILL to believe or disbelieve in God.

Surah 73:19
Lo! This is a Reminder. Let him who will, then, choose a way unto his Lord.
Surah 25:57
Say: I ask of you no reward for this, save that whoso will may choose a way unto his Lord.
Surah 80:11-12
Nay, but verily it is an Admonishment, So let whosoever will pay heed to it,

These verses clearly show that human beings have the FREE WILL to choose a path unto the Lord.
Surah 29:69
As for those who strive in Us, We surely guide them to Our paths, and lo! Allah is with the good.

God is clearly telling us that we need to struggle hard in order to find the path to God. Allah will only guide those who actually struggle to be guided. If God has already predetermined who would go to hell and heaven without giving us free will then it would be useless for Allah to tell us to strive to be good. So God guides those who strive and put an effort to want to be guided.

Surah 39:7
If ye are thankless, yet Allah is Independent of you, though He is not pleased with thanklessness for His bondmen; and if ye are thankful He is pleased therewith for you. No laden soul will bear another's load. Then unto your Lord is your return; and He will tell you what ye used to do. Lo! He knoweth what is in the breasts (of men).

Allah is saying that he is not pleased with those who are thankless to Him. It would not make sense for God to misguide those people intentionally without giving them free will so that they can go and do what He does not like.


Surah 45:22

And Allah hath created the heavens and the earth with truth, and that every soul may be repaid what it hath earned. And they will not be wronged.

God will judge those people according to the deeds that they have done and according to what they earned. They will not be judged unfairly.
So God judging them by what they earned shows that human beings have free will to do evil if they are judged to be evil and therefore it is no one's fault but theirs.

Surah 45:15
Whoso doeth right, it is for his soul, and whoso doeth wrong, it is against it. And afterward unto your Lord ye will be brought back.
Surah 27:90
And whoso bringeth an ill-deed, such will be flung down on their faces in the Fire. Are ye rewarded aught save what ye did ?
Surah 37:38-39
Lo! (now) verily ye taste the painful doom - Ye are requited naught save what ye did -
Surah 52:13-19
The day when they are thrust with a (disdainful) thrust, into the fire of hell (And it is said unto them): This is the Fire which ye were wont to deny. Is this magic, or do ye not see ? Endure the heat thereof, and whether ye are patient of it or impatient of it is all one for you. Ye are only being paid for what ye used to do. Lo! those who kept their duty dwell in gardens and delight, Happy because of what their Lord hath given them, and (because) their Lord hath warded off from them the torment of hell-fire. (And it is said unto them): Eat and drink in health (as a reward) for what ye used to do,
Surah 7:147-148
Those who deny Our revelations and the meeting of the Hereafter, their works are fruitless. Are they requited aught save what they used to do ? And the folk of Moses, after (he left them), chose a calf (for worship), (made) out of their ornaments, of saffron hue, which gave a lowing sound. Saw they not that it spake not unto them nor guided them to any way ? They chose it, and became wrong-doers.

Again, clearly we see that sinners are punished for what they did. It is their fault and no one else's.

Surah 10:45

And on the day when He shall gather them together, (when it will seem) as though they had tarried but an hour of the day, recognising one another, those will verily have perished who denied the meeting with Allah and were not guided.
Surah 16:33-34
Await they aught say that the angels should come unto them or thy Lord's command should come to pass ? Even so did those before them. Allah wronged them not, but they did wrong themselves, So that the evils of what they did smote them, and that which they used to mock surrounded them.
Surah 41:46
Whoso doeth right it is for his soul, and whoso doeth wrong it is against it. And thy Lord is not at all a tyrant to His slaves.
Again we see that Allah is not to be held responsible but the sinners are for their own sinful actions that they willingly chose to commit.
So Who Are The People That Are Misguided?
Surah 2:26
Lo! Allah disdaineth not to coin the similitude even of a gnat. Those who believe know that it is the truth from their Lord; but those who disbelieve say: What doth Allah wish (to teach) by such a similitude ? He misleadeth many thereby, and He guideth many thereby; and He misleadeth thereby only miscreants;
Surah 22:4
Against him it is written down that whoever takes him (the devil) for a friend, he shall lead him astray and conduct him to the chastisement of the burning fire.
Surah 7:30
A party hath He led aright, while error hath just hold over (another) party, for lo! they choose the devils for protecting supporters instead of Allah and deem that they are rightly guided.
Surah 33:36
And it becometh not a believing man or a believing woman, when Allah and His messenger have decided an affair (for them), that they should (after that) claim any say in their affair; and whoso is rebellious to Allah and His messenger, he verily goeth astray in error manifest.
Surah 14:27
Allah confirmeth those who believe by a firm saying in the life of the world and in the Hereafter, and Allah sendeth wrong-doers astray. And Allah doeth what He will.
Surah 25:44
Or deemest thou that most of them hear or understand ? They are but as the cattle - nay, but they are farther astray ?
Surah 33:67
And they say: Our Lord! Lo! we obeyed our princes and great men, and they misled us from the Way.
Surah 17:72
Whoso is blind here will be blind in the Hereafter, and yet further from the road.
Surah 6:116
If thou obeyedst most of those on earth they would mislead thee far from Allah's way. They follow naught but an opinion, and they do but guess.
Surah 6:56
Say: I am forbidden to worship those on whom ye call instead of Allah. Say: I will not follow your desires, for then should I go astray and I should not be of the rightly guided.

So we see that Allah misguides those wrongdoers who are truly misguided by their own actions that they willingly chose to commit. Allah is omniscient and therefore knows in advance what their FREE WILLING actions will be. Therefore, Allah misguides them. HOWEVER, Allah only misguides those who WILLINGLY commit wrong and have earned to be labeled as disbelievers and go to Hell.
Let me give an example from the Bible...

Isaiah 19:14

The LORD has poured into them a spirit of dizziness; they make Egypt stagger in all that she does, as a drunkard staggers around in his vomit.

So here we see that God poured a spirit into man that caused them to do bad things. Now obviously Christians are going to reply back saying that the Egyptians had free will and that God did not force the spirit to force them to do bad. So if Christians are going to interpret it that way then why do they come and start attacking these Quranic verses?
