«يَا دَاخِلْ بِينِ الْمِسْكْ وِالرِّيحَهْ مَا يْنُوبَكِ الَّا الْفِضِيحَةْ»

This saying warns against involving yourself in business that is not yours. Whoever forces a way into matters where he has no part should expect to gain nothing but embarrassment and unwelcome words, since uninvited meddling tends to rebound on the meddler.

The image is probably of someone who squeezes himself in among fine perfumes such as musk. Amid such sweet odors, whatever smell he carries would likely be noticed at once, leaving him exposed. This reading of the image is likely but not settled, and the warning against meddling holds either way.

Say it to warn someone who is about to interfere in matters outside their concern, or afterward when a meddler has ended up embarrassed. It works as frank, informal advice or a light rebuke.
