The Palestinians

The פייטן in קינות לתשעה באב #37 writes,
"בך כל בהמה ועוף חכמו עדי כחמור היה לפנים לבן יאיר חמוריך"

"Within you (Zion) every animal & bird grew wise to the point where even the donkeys were as intelligent as the donkey of (Pinchas) Ben Yair".
(ie: Animals in Eretz Yisroel are smarter than Chutz La'aretz animals)

It is claimed, that the most intelligent Arabs, are the Palestinians.

Perhaps, the reason for it is, because if אוירא דארץ ישראל has an effect on the חמורים it surely must also have an effect on the עם הדומה לחמור

However, we must apply the Talmudic rule of דיו לבא מן הדין להיות כנדון.

In a קל וחומר we limit the חומר to the same measure as the קל.
Therefore the קל וחומר teaches us that the ישמעאלי has as much
intelligence as the Israeli חמור but not more.
