The 7th century - 600s AD.
So referring to before the 4th century A.D. is another moot point.
Not regarding the Islamic fables that were all created and put to the pen in the 8th to 10th centuries AD, regarding Islam's false claims of anything ever having gone on in Mecca prior to the 4th century when it was initially settled. To claim otherwise is demonstrably pure Islamic hogwash that Muhammad's followers are stuck labeling "tradition" since it is completely unhistorical. As further explored of your feeble efforts, in the subject of Abraham, Hagar and Ishmael that I split off at this link:

Response: Ahh. I was waiting for you to say it was copied. Well, this can be easily disproven from the Qur'an challenge. What is that challenge?
"It is humanly impossible for a person/s to inspire enough followers to help him/her/ them conquer and rule a nation by using human-made speech/literature that goes against the likes and beliefs of those people."This is the miracle of Muhammad. For the challenge proves that it is humanly impossible to use any speech or literature that goes against the majority and is invented by a person/s, to inspire enough followers amongst them to help to conquer and rule a nation. The skeptic still disagrees? Then take the challenge and prove differently. Try using a speech or literature that does not agree with the likes of a majority of people that is an invention by a person/s. Then use that very same speech to inspire them to conquer a nation for you to rule and see what happens. The challenge can even be simplified by asking a skeptic to just conquer and rule the street that he or she lives on and see what happens. Yet the person will fail and fail miserably. No person will come close to achieving the challenge. Any individual, when taking the challenge, will have a first-hand eyewitness account from experience and observation that such an act is humanly impossible and that is when the person will learn the miracle of Muhammad. Why? The reason is because Muhammad used the Qur'an to inspire enough followers to help him conquer and rule a nation in the same fashion. So since it is humanly impossible to use human-made speech or literature that goes against the likes of the masses to inspire them to follow a person/s to help conquer and rule a nation, yet Muhammad used the Qur'an to do just that, then what does that mean? That means that the Qur'an that Muhammad used is not the invention of any human but must come from a higher power and authority greater than humans, and that is Allah. Do the skeptics still disagree? Then take the challenge and prove differently. When the challengers fail, because they will, this will help to demonstrate that the Qur’an is of divine origin as proven by the scientific method itself because it provides a hands-on eyewitness account that producing something like the Qur’an is humanly impossible. If you read this, and you yourself disagree, then take the challenge and prove differently.
