muslim festival significantly

 only 2 weeks until a MAJOR muslim holiday... i almost joined  them when i searched religions, but praise alla r.r. the merciful and gracefull, i did not get tricked nor fooled.

the object of celebration has 2 MAJOR issues. tradition is "our ancestor ishmael agreed to be a sacrifice by his father abraham" that is THEIR faith, if so the claim "jews stole land from canan" they admitted different family and preserved in a festival as above.
in mention ismail ishmael we must emphasize that quran called bible truth and light so not corrupted. god who knows future called bible good and light, the bible said god gave "his product" the land by jordan river to jacob, bible chapter 32? so not anyone else, for example ishmael. ishmael was "of flesh" family but "not all flesh is son" excluded ishmael as above creator gave product to jacob.
to deny genesis would violate quran that god who KNEW future called good... this pincer pushed educated muslims away from muslim teachers, who claimed corrupted to students who sccrptedvquran with the praisevof bible as sbove. many left islam to OBEY quran that bible good
toward christian bible and one famous one got so oppressed she had to flee her country to a western one.
my point is their own faith, that they teach is we are ishmael who was different than jacob and canan.
the second issue seems to me and westerners minor , and purely academic but the issue is HUGE if you live among muslims.
the quran in chapter 37 sura, sections 95 to 105 retells the story of abraham and the decision to "sacrifice his son" those are the words... and anyone who knows arabic letters can easily inspect NO NAME.
obviously, not saying either way, allows more than one option, so interpretations developed. still the objective FACT is no name and forbidden to subtract nor ADD even one word to quran.
so when a particularly naive academic was foolish enough, in 2022, to say this fact, last years adha,  in a group with a part muslim... the emotions exploded.
the academic said his opinion and found the flaws in the claims  of the part muslim.
he foolishly challenged him to open the book. he even begged if you show me the source I will apologize.
i dont comprehend the big deal if name written or not but the muslims make a  huge fuss... which if true then lost land as above.
perhaps interpreting ismail is valid but... the methods of context and as above even quran said bible true so relied on bible for name of son, and other context methods isac the prophet is mentioned nearby with the "promise" as above land.
if muhamed pbuh wanted to teach different than bible, that was available that generation he cant skip name if another version existed.
at one point in the argument the part muslim shouted "stop saying wrong. muslims will kill you" well he knows his culture better than westerners so ONLY read and know but do not risk mentioning this fact to muslim do not risk maybe they wont hit you.
