The ruling on items gilded or mixed with some gold and silver

Question:
O Shaykh, I have informed you, may Allah reward you, is everything that is called gold and silver considered as such, or is it only what I can separate and evaluate?

Answer:
Yes, this is a question about items gilded or mixed with some gold and silver. The jurists say that if something can be extracted from it, it is forbidden. However, if nothing can be extracted from it, and it is merely a slight polishing from which nothing can be extracted, then this is not considered forbidden, although the precaution is to avoid this thing as much as possible. Avoid this thing as much as possible. For this reason, they said, for example, regarding the buttons on the bisht, that it is of this type, that nothing can be extracted from it, nothing can be extracted from it. The embroidery on the bisht, this embroidery, is not prohibited and is not forbidden because nothing can be extracted from it when it is separated, so there is no harm. Also, the Messenger (peace and blessings be upon him) granted a dispensation for the embroidery to be of silk in the garment, and they analogized it to that, saying this is like the embroidery. Yes.
