The ruling on using a pen and a watch mixed with gold

Question:
Is it permissible to use a watch or a pen that is mixed with a small amount of gold?

Answer:
No, it is not permissible to make a pen or an inkwell out of gold or silver; it is not permissible, even if it is a small amount. This was only permitted in weapons out of necessity, and in the adornment of the belt with which one girds oneself, meaning decorated with the color of silver or with something. This is permissible. The belts that people wear to gird themselves for necessity, or in weapons, where there is some gold in the scabbard or in the hilt of the sword, this was found during the time of the Prophet (peace and blessings be upon him) and was not prohibited. This is specific to weapons.
