In the Christain Bible Abraham is known as Abram at first, and then God is said to change his name to Abraham, Sarah was named Sarai and changed to Sarah. These were the first Father and Mother of all Jewish people. In the
, Quran, the only name given to Abraham is "Ibraheem" and "Ibrahaam", all sharing the original root, b-r-h-m. But, to Islam, the Hebrew and Christainity he is held in very very high estem.
Assyriologists suggest that the Hebrew letter Hê (h) in the Minnean dialect is written in stead of a long ‘a’ (ā), and that the difference between Abraham and Abram is merely dialectical. The same can be said for the names Sarai and Sarah, as their meanings are also identical.

Don't forget there's also manyreferences of Jesus since he's highly revered by Muslims - his name appears in the Quaran as Isa. There is also a similar account of revelations & the Apocalypse where Isa is the main character. He appears with the last 2000 true Muslims, surrounded by the armies of Dajjal. Isa (and only Isa) defeats Dajjal in the last battle. Dajjal being the "deceiver" aka the anti-christ & only Isa can kick his ass!!

Yes, I have read the Quaran as well. And you are correct. The biggest issue is the languages all Biblical Text were in from Hebrew, Arabic, Greek, Latin, and English to mention just a few. In the Quaran Jinn are the same as demons in Christain Bibles. And many of the 777 lost Holy Books are relative to the old testimate and the Quaran. Even President Trump read the Quaran.

I think the meaning of "demon" has been misconstrued over time. The word stems from the ancient Greek translation, meaning spirit guides or the beings between god and humans. My understanding of the Jinn is that there are "evil" Jinn and "good" Jinn & the extent to which we sway (in action, good or evil) towards one or the other determines which we're more connected to. The same could be applied to the "demon" of ancient Greek, I'd say and they're most likely equivalent to "angels" (ie: there are good angels & evil angels). Even the "watchers" (from the Summerian stories) where they split into being either the Protectors of humanity or the Persecutors of humanity. The language in each translation and the meaning of the terms in each can definitely complicate things. The context can get skewed without an understanding of how each language interprets the words. I always try to trace them backwards to try and grasp the closest connection to the meanings. So interesting though!
