what is the ruling on the threads found on men's clothing as we have doubts that they are mixed with gold?
Experts were formerly asked about threads which are put on the edges of clothing as a means of decoration and which look like gold but they said that such threads do not contain any kind of gold. Accordingly, it is Mubah (permissible) to put this kind of threads on clothing. Even if some gold is involved, it is of very small amount and consequently it is also Mubah because it is subjoined to the article of clothing. However, if a man knows for sure that the threads in question contain a lot of gold, wearing that clothing will be considered Haram (prohibited).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
