«اِلْعَوِيلْ مَا يِفْتَحْ بَابُهْ»

The proverb uses an open or shut door as a measure of character. Here عويل is a colloquial term for a base, worthless person, not the Standard Arabic sense of loud wailing. Such a person keeps his home closed to guests, while opening the door freely belongs to someone generous and noble.

In practice, the saying ties hospitality to worth. Whether a person welcomes others shows what kind of person they are, and refusing guests marks someone as petty. The remark can serve as a rebuke to a stingy individual or as quiet praise for a host who receives people gladly.

Use it to criticize someone who withholds hospitality or turns visitors away, or to contrast them with a generous host. It is a pointed judgment of character, not a neutral description of a closed home; aimed at a real person, it calls them petty and stingy and can insult.
