Hospitality requires that hosts try their best to care for all their guests’ needs. Even if they are not sure that the guests will partake of what is prepared for them, the hosts should nevertheless provide abundantly for them.
Similarly, although living frugally is a value found in the Torah, it is one we should impose on ourselves, not on others. When we think about providing for a poor family, for example, we should not provide them with only their bare necessities, but with enough to allow them to live according to a dignified standard of living.1


What is “a dignified standard?”
A standard that allows someone to have self respect and not feel ashamed, in my opinion.
A standard is a cultural normal. what is standard for Jews, is not standard for gentile.
The same for Muslims. You treat others with respect. I believe it goes something like “love your neighbor, and the stranger as yourself”.
Shabbat Shalom,
Doesn't the Torah "set" the standard for Jew, Gentile, and Muslim? ". . . Love your neighbor as yourself, I Am The LRD" [Leviticus 19:18]. Cultural expression interprets and extends that "Command" to our neighbors as us showing the Love of GD [underscore].
