That’s true.
Perhaps you wanted to say “Ibrahimi school of thought”.
because
Hanafi school of thought takes its name after Imam Abu Hanifa ah, and thus came AFTER hazrat Khadijah pbuh (and not before).
Or perhaps you meant to say something entirely different and mistyped “hanafi” instead.
She certainly inspired Mohammed pbuh. She was an excellent companion. She was older, wiser, and operated a large successful “woman-owned” business. Thus pretty similar in “business sense” to, if not better than many modern day women business leaders.
I have not seen clearly any reference to Hazrat Khadijah’s pbuh family being the follower of Eesah pbuh.
However one thing is for sure. Hazrat Khadijah ra was very much familiar with Eesa-hi pbuh philosophy.
In fact it is recorded by many, that she is the one who asked Mohammed pbuh to go visit a padri in Makkah. yes there used to be churches in Makkah until us Muslims destroyed them all.
After the first Wahi, and a visit from Hazrat Jibraeel ah, Mohammed pbuh was pretty stressed out. So when he came home, Hazrat Khadijah calmed him down, and (perhaps few days later) asked Him pbuh to go visit the padri and discuss with him the Wahi.
And theChristian padri was perhaps the very first “religious man” who reaffirmed to Mohammed pbuh that yes, Allah swt has indeed spoken to Him pbuh.
Thus there was a close interaction between Hazrat Khadijah pbuh and the local church leaders for sure.
