The ruling on using pens and watches gilded with gold

Question:
Or another shaykh, may Allah grant you success, what is the ruling on using pens gilded with gold, and likewise weapons that are gilded?

Answer:
It is not permissible. It is not permissible for men to wear anything gilded with gold, because the Prophet (peace and blessings be upon him) said regarding gold and silk: “It is lawful for the females of my Ummah and forbidden for the males.” And when something is forbidden, its prohibition extends to its parts as well; the prohibition of a thing is a prohibition of its parts. So if there is gold on the watch, or if the pen contains gold, it is not permissible. The watch is not permissible for a man, but it is permissible for a woman. As for the pen, it is not permissible for men or women; a gold pen is not permissible for men or women, just like a vessel. A gold vessel is not permissible for a man or a woman to drink from. It is only permitted for a woman to adorn herself with gold on her body. As for her making vessels or keeping gold ornaments in her house, that is forbidden and not permissible, just as it is for men. Yes. What is on the sides of the... that does not establish that it is gold... In any case, this... engaging in it leads to... Ah. So if it is gilded with gold and it is established that it is gilded with gold, it is not permissible. But if it is not established that it is gold, and what is in it is not gold but is merely called gold, being made of another material that has the color of gold, then there is no harm in it. Now, regarding gold, if you verify that this color is gold, it is not permissible. Yes.
