The רבינו בחיי writes, (Breishis 21:14)
"Avraham Avinu saw with his נבואה
that his children the Bnei Yisrael will
suffer in the future from ישמעאל.
No other nation will hate the Bnei Yisrael
as much as the ישמעאלים therefore he
treated his son as an enemy and supplied
him with bread & water, the way it says
in Mishlei (25) אם רעב שונאך האכילהו לחם
ואם צמא השקהו מים"
Even though the Nazis killed six million
Yidden, however as much as they hated
Yidden the ישמעאלים hate us even more.
The Nazis weren't Moser Nefesh to kill
Yidden whereas the ישמעאלים would
commit suicide to Ch"v kill Yidden אמבצי
