Q 1: Is it Haram (prohibited)
to sell gold for men,
whether pure or impure? Given that the used gold is 14-, 18- or 21-carats. Is it considered a major or a minor sin?
The One Who permits and prohibits things is Allah and His Messenger (peace be upon him). A Mukallaf (person meeting the conditions to be held legally accountable for their actions) is responsible for their own actions, whether in sayings, deeds or beliefs. If a person finds something difficult in the matters of religion, they should ask the scholars, as Allah says,
So ask the people of the Scripture, if you do not know.
The state does not forbid selling it, because it is worn by women and it is Halal (lawful) for them. It is also known to all Muslims that it is forbidden for men.
Q 3: If it is established that it is Haram, what should we do with the huge amounts of gold we have, especially that they constitute at least half of our trade, and it is estimated at millions?
The gold which is not suitable for women to wear might be transferred into something that is suitable for them, or the part of it which is suitable for women, sold to them. (Part No. 13; Page No. 483)
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
