«اِللِّي مَاهُوشْ وَاخِدْ عَ الْبُخُورْ يِنْحِرِقْ دِيلُهْ»

The saying warns that ignorance of a practice can turn an ordinary attempt into self-inflicted harm. It pictures someone handling incense without knowing the necessary precautions and accidentally scorching a trailing hem.

It is applied to a person who ventures into an unfamiliar activity without understanding how it works, then suffers the consequences. The image is a caution about practical unfamiliarity, not a claim that all unfamiliar activities are inherently dangerous.

Use it as a cautionary remark when someone takes up a task, custom, or technique they do not understand and risks causing trouble for themselves. It can also comment after a predictable mishap resulting from unfamiliarity.
