Praise be to Allah.
If the matter is as described, it is not permissible to sell vessels and medical equipment that is plated with gold or silver to either men or women, because the Prophet (peace and blessings of Allaah be upon him) said: “Do not drink from vessels of gold or silver, and do not eat from plates made (of gold or silver). They are for them in this world and for us in the Hereafter.” Saheeh – agreed upon.
And the Prophet (peace and blessings of Allaah be upon him) said: “The one who eats from a vessel of silver is taking fire from Hell into his belly.” Saheeh – agreed upon; this version was narrated by Muslim.
All other uses that have to do with food and drink are also forbidden, because of the general meaning of these reports and so as to prevent the means that may lead to evil.
Similarly it is not permissible for men to use watches and spectacles that are gold-plated. And it is not permissible to sell such items to men.
May Allaah help us and you to do all that is good.
