The Palestinians

אוירא דארץ ישראל מחכים ב"ב קנ"ח ע"ב  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 Ben Yair". With this Piyut we can understand why the need for Avraham who was a צדיק to muzzle his animals and couldn't rely on - בהמתן של צדיקים אין הקב"ה מביא תקלה It was during the times they were in חו"ל only then was it necessary to muzzle them. The rule of בהמתן של צדיקים only works on animals in ארץ ישראל whose intelligence is higher than animals in  חו"ל Some claim, 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, the rule of דיו לבא מן הדין להיות כנדון applies.
