Having lived in Saudi Arabia for some time, I appreciate their view of what constitutes a fine person. These tales show their strong sense of hospitality and humor, and that common sense is more valuable than money.
Being hospitable to visitors comes from the Arab's long lives in the sands and deserts. By not sharing one's water and food, you probably sent that visitor (or group) to their deaths. The desert is an unforgiving land to inhabit. Therefore, Arabs learned early that being hospitable to people they encountered was critical. In olden times, men became important figures in their world by being known to be hospitable to all. Thus, it is realistic to expect stories lauding hospitality and generosity.
A sense of humor and having common sense are highly valued in Arab culture. These stories show how these attributes help people get along with their neighbors and trading partners.
This short collection is charming and shows the Arab mind to Westerners, who might not otherwise encounter it.
