If you looked at the stories mentioned in the holy quran you'll find that most of them if not all of them came from both the bible and the talmud with few edits here and there to make them seem different .
The cause of that is muhammad went every year with merchant caravan together with Waraqah Ibn Nawfal which is the maternal uncle of Muhammad via Khadijah, Muhammad's first wife. His presence in the story of Muhammad is so problematic. Most people who believe in Islam never heard about him. Those few who did, are just given a "quick" passing by mentioning in their Islamic classes. Yet, even by Islamic standards, he was a very important figure. Some see him as the first person to believe in Muhammad even before the first message had arrived.
Who is this man? Waraqah was a priest in Christianity and Judaism. He is Nestorian priest. Waraqah lived a long life and died of old age shortly after Muhammad got his first message also muhammad went with him as he would go with merchant caravan.
His story throws big concerns to the claim that Muhammad's message came from Allah or via his angel Gabriel - especially when Islam ended up near carbon copy of Nestorian faith (a mixture of Christianity and Judaism). It shows Muhammad had access to the knowledge. On top of that it shows even more that the Kuffar of Mecca tolerated all faiths, including having a priest among their ranks (Waraqah would have been a Quraishi). It proves what Islamic text sort of admit, that the Kabaa was open liberal place for all people to practice whatever faith they have in peace by the fact many gods were allowed on display. It proves that the Kuffar never harmed those who did not follow their gods. Khadijah, a very successful business women in her own right, was a monotheist and most probably Christian Nestorian like her uncle - some Islamic scholars may disagree this shows the feminist view of those Kuffar and place any nonsense about how women were treated back then into the trash -like islamic claims of women being oppressed back then- .
When did the people of Mecca have issues with Muhammad? When Muhammad started to insult their gods, when they would wake up in the morning and find the statues of the gods dessicated and damaged, when Muhammad mock them that their gods are useless! Talk about tolerance??
But for me, this hadith throws the doors wide open on the story of Waraqah. The hadith suggest that shortly after Muhammad started getting the revelations "....But a short while later Waraqa died and the Divine Inspiration was paused (stopped) for a while so that Allah's Messenger (ﷺ) was very much grieved." Sahih al-Bukhari 4953
This proves Muhammad knew the man very well, and likely behind his inspiration!
