The errors in Quran disqualify the Quran as the word of God, who is perfect and does not make errors.
Many of the errors in Quran are self-contradictions that naskh tries to cover up. But the Quran also has archaeological errors, historical errors, errors in logic and even elementary mathematics.
For example, the Quran claims that one night, God took Muhammad to the "al-Aqsa" mosque is in Jerusalem:
"Exalted is He who took His Servant by night from al-Masjid al-Haram to al-Masjid al-Aqsa, whose surroundings We have blessed, to show him of Our signs. Indeed, He is the Hearing, the Seeing." - Quran 17:1
The Muslim army conquered Jerusalem in 637 AD and the al-Aqsa mosque was completed in 705 AD. The problem with the above passage in the Quran is that Muhammad died in 632 AD, which was 5 years before the Muslim army reached Jerusalem and 73 years before the al-Aqsa mosque was built.
Or consider Quran 20:92-95, which claims that Moses confronted "Aaron" and a "Samaritan" for having made the golden calf for the Israelites while he (Moses) was on Mount Sinai:
"[Moses] said, "O Aaron, what prevented you, when you saw them going astray, from following me? Then have you disobeyed my order?" [Aaron] said, "O son of my mother, do not seize [me] by my beard or by my head. Indeed, I feared that you would say, 'You caused division among the Children of Israel, and you did not observe [or await] my word.'" [Moses] said, "And what is your case, O Samaritan?" - Quran 20:92-95
Assyria conquered the Jewish northern kingdom in 722 BC, exiled its upper class and brought in conquered people from other lands, who intermarried with the lower class Jews who had been allowed to stay. Their offspring were called "Samaritans" because they occupied the region of "Samaria", which was named after its original owner, "Shemer" (see 1 Kings 16:24 in the Bible). The Jews despised the Samaritans both for being a mixed race and for setting up their own temple to compete against the temple in Jerusalem.
But the golden calf incident near Mount Sinai mentioned in Quran 20:92-95 above took place in 1446 BC, which was 725 years before the first Samaritan was born in 721 BC
How old was Mary when she had Jesus?
It gets worse. For example, how old was Mary when she had Jesus?
Certainly, Mary wasn't as old as the lady on the right when she had Jesus? According to the Quran, Mary was actually older than the lady on the right when she had Jesus:
"Then she brought [Jesus] to her people, carrying him. They said, "O Mary, you have certainly done a thing unprecedented. O sister of Aaron, your father was not a man of evil, nor was your mother unchaste." - Quran 19:27-28
"And Mary, the daughter of Imran, who guarded her chastity, and We breathed into (her body) of our spirit; and she believed in the words of her Lord and of His revelations, and was of the devoutly obedient." - Quran 66:12
There are a number of Mary - also spelled "Maria" or "Miriam" in English - in the Bible. One of them is the mother of Jesus:
"Now the birth of Jesus Christ was as follows: after His mother Mary was betrothed to Joseph, before they came together, she was found with child of the Holy Spirit." - Matthew 1:18
But the Mary who is the "daughter of Imran" (spelled "Amran" in the Bible) and the "sister of Aaron" was the sister of Moses who lived in the 15th century BC:
"The name of Amram's wife was Jochebed the daughter of Levi, who was born to Levi in Egypt; and to Amram she bore Aaron and Moses and their sister Miriam." - Numbers 26:59
Therefore, unless Mary was 1,500 years old when she had Jesus - indeed, unless Joseph married a 1,500 year old virgin - Muhammad mistook two different women in the Bible as the same.
Why does the Quran contain such glaring errors?
The proximate reason is that Muhammad was illiterate and therefore could not read the Bible, and had only a vague and often incorrect knowledge of it.
The ultimate reason, of course, is that Muhammad was a false prophet who did not speak for God and who tried to cover up this and other glaring errors in his Quran with naskh.
Naskh, or al-naskh, means abrogation - i.e., change or repeal.
Naskh is Muhammad's supposedly God-given right to change or repeal God's previously given revelations. Over 220 verses in the Quran remain abrogated via naskh.
Muhammad justified naskh with this passage in the Quran:
"We do not abrogate a verse or cause it to be forgotten except that We bring forth [one] better than it or similar to it. Do you not know that Allah is over all things competent?" - Quran 2:106
Does God, who is perfect, need to change, repeal or "better" His own words even once, let alone over 220 times in the life of one self-declared prophet?
In reality, naskh is a dubious but convenient tool that Muhammad used to cover up his errors in Quran, changes his mind, and on at least three occasions, even excuse to his sexual appetite. For example, Muhammad initially limited all men to each have a maximum of four wives (above):
"And if you fear that you will not deal justly with the orphan girls, then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one or those your right hand possesses. That is more suitable that you may not incline [to injustice]." - Quran 4:3
Naskh of the passage above with the one below granted Muhammad the sole privilege to take as many wives as he wanted:
"O Prophet, indeed We have made lawful to you your wives to whom you have given their due compensation and those your right hand possesses from what Allah has returned to you [of captives] and the daughters of your paternal uncles and the daughters of your paternal aunts and the daughters of your maternal uncles and the daughters of your maternal aunts who emigrated with you and a believing woman if she gives herself to the Prophet [and] if the Prophet wishes to marry her, [this is] only for you, excluding the [other] believers. We certainly know what We have made obligatory upon them concerning their wives and those their right hands possess, [but this is for you] in order that there will be upon you no discomfort. And ever is Allah Forgiving and Merciful." - Quran 33:50
Muhammad's Favorite Wives
Second, Quran 4:129 states Muhammad's prohibition of polygamous husbands having sex with only their favorite wives while leaving other wives "hanging":
"And you will never be able to be equal between wives, even if you should strive. So do not incline completely [toward some wives] and leave another hanging. And if you amend and fear Allah - then indeed, Allah is ever Forgiving and Merciful." - Quran 4:129
Then Quran 33:51 stipulating Muhammad's sole right to prefer his favorite wife and "put aside" the non-favorites conveniently occurred to him:
"You, [O Muhammad], may put aside whom you will of them or take to yourself whom you will. And any that you desire of those [wives] from whom you had [temporarily] separated - there is no blame upon you [in returning her]. That is more suitable that they should be content and not grieve and that they should be satisfied with what you have given them - all of them. And Allah knows what is in your hearts. And ever is Allah Knowing and Forbearing." - Quran 33:51
Third, when Muhammad wanted for himself Zaynab, the wife of his (Muhammad's) adopted son, Zayd, Muhammad's desire was made known to Zayd, who "offered" to divorce her, at which point Quran 33:4 and 33:37 suddenly occurred to Muhammad, declaring that an adopted son is not a son and that Zaynab specifically had been given to Muhammad by divine intervention:
"Allah has not made for a man two hearts in his interior. And He has not made your wives whom you declare unlawful your mothers. And he has not made your adopted sons your [true] sons. That is [merely] your saying by your mouths, but Allah says the truth, and He guides to the [right] way." - Quran 33:4
"And [remember, O Muhammad], when you said to the one on whom Allah bestowed favor and you bestowed favor, "Keep your wife and fear Allah ," while you concealed within yourself that which Allah is to disclose. And you feared the people, while Allah has more right that you fear Him. So when Zayd had no longer any need for her, We married her to you in order that there not be upon the believers any discomfort concerning the wives of their adopted sons when they no longer have need of them. And ever is the command of Allah accomplished." - Quran 33:37
