«كُلُّهْ عَنْدِ الْعَرَبْ صَابُونْ»

The saying mocks a person who cannot tell things apart and treats very different items as if they were identical. Its word for "Arabs" here means Bedouins or desert dwellers, not Arabs as a whole; the picture is of them lumping every unfamiliar substance together as "soap," overlooking obvious distinctions.

In use, it remarks on indiscriminate judgment: someone lacking knowledge or discernment sees no difference between good and bad or fine and coarse, so careful choices are wasted on them. It has a condescending edge, drawing on a town-dweller's stereotype of nomadic ignorance.

Use it to comment on someone who fails to notice differences that matter, such as quality, value, or kind, often when effort or refinement goes unappreciated. Because it depends on a demeaning stereotype of Bedouins, confine it to discussion or quotation rather than applying it to real people.
