What is the biggest mistake of the Quran?

The Koran is the biggest source of Islam. The Koran author himself has claimed that the Qur'an is a clear and accurate book for humanity to guide the world till the end. The Qur'an is revealed to the Prophet Mohammed. Mohammed is such a person who has never done or has done wrong in his life.

But on the page every page opens the Koran on the wrong information of scientific data, mathematical errors, historical mistakes, grave mistakes ... mistakes ... mistakes ... mistakes ...
Forget us forgot Bashundhara It is difficult to find out what is wrong with the mistakes of the Qur'an in countless mistakes. Although difficult, however, today we are trying to re-introduce a familiar mistake.

Point 01
Koran Verse 18: Verse 86
"When he (Zul-Qarnain) reached the setting of the sun, he saw the sun hanging in a muddy lake and he saw a community there, and I said," O Dhulkarnain, you can punish them or accept them kindly. "

The question is from the verse
01. Is there a place in the world where the sun sets?
0. If not, then it is possible for anyone to go to the sun?
03. Allah has made it clear that a person named Zulkarnain went there and watched the sun set in the muddy waters and there were some people and living there. Why is that?

Now the Muslim brothers will come and answer that "in fact Allah did not say that the sun sets in a murky water. All that Allah has said is that Zulkarnainen is a person who has seen ..."
The question remains from that sentence,
04. Since there is no place on earth in sunset, it is not possible for Zulkarnain to go there too. Then the kulkarnain khicha lies really? So how did this false kacha place in the Quran ??

Point 2:
If there is a problem arising out of any verse of the Qur'an, then we read the commentary of that verse and related hadiths related to it. Let us now see what the hadith related to this verse

Narrated from Abu Da'a: At one time I was sitting on the back of the Prophet of Allah while sitting on the donkey during sunset. Then the Prophet of Allah asked, "Do you know where the sun goes?" I said, 'Allah and His Prophet know better.' Then he said, "It gets set in a hot water pond" [Sunan Abu Dawud 3991]

The questions that can be asked from that hadith
1. It is more obvious than the sun where the sun sets?
2. Is it not proved in the Hadith that Mohammed realized the Qur'an's verse, actually the sun set on the earth in any water?
3. Is it possible to clear the fact that Mohammed and Koran writers are not allowed to recognize?
4. What are you thinking about these verses and traditions? Leaving all the science subjects and blindly holding religion? Or, of course, Mohammed or Koran, who is trying to find the reason for defying the author? Or are you thinking of leaving the religion of morality by leading your conscience? Choice is yours!
