[Ali Imran]

Midrash Rabbah (Genesis Rabbah 53:16):
This Midrash discusses Ishmael and mentions that he was involved in idol worship. It states that he and his descendants worshipped idols and that they were not initially followers of the worship of the one true God.  

Example: "And Ishmael dwelled in the presence of his mother Hagar in the land of Egypt and of the Ishmaelites, who worshipped idols."
(Genesis Rabbah 53:16)

Talmud (Sanhedrin 89a):
The Talmud notes that Ishmael's descendants engaged in idol worship, implying that their practices were not initially aligned with monotheism.  

It discusses that Ishmael's descendants were known for their idolatry, though this is not a direct condemnation of Ishmael himself.

Midrash Tanchuma (Vayera 11):
It mentions that Ishmael was not a worshipper of the true God initially, but through Abraham's influence, some of his descendants eventually turned towards monotheism.

It says Ishmael's descendants, not Ishmael. And nothing in the Bible says Ishmael was worshipping a false god.

So your statement about Ishmael is false. You like making false statements.
