Riba in Manufactured Goods from Riba Commodities

Another questioner:
Naturally, the matter is now in one text. Manufacturing.

The Shaykh:
If it changes, if it shifts from being weighed or measured, it shifts to being a manufactured item, such as iron becoming vessels, or becoming pots, or becoming cars, then riba does not apply to it. It shifts from being a riba commodity to being a non-riba commodity. It is permissible to sell one car for two or three cars. It is permissible to sell one vessel for two or three vessels, as long as there is no contradiction, because it has become a non-riba commodity. Yes. Gold is not like this; it is weighed and remains weighed even if it is manufactured; it is sold by the gram. Yes.

Another questioner:
when.

The Shaykh:
If one sells cast metal for non-cast metal, equality in weight is required.

Another questioner:
Manufacturing, I believe.

The Shaykh:
No, manufacturing is not intended here, nor is it considered, because it is sold by the gram, not by count; it is sold by the gram. Yes.
