Is it permissible to participate in the design and construction of a cosmetics factory for a foreign company, taking into consideration that the raw materials are unknown, the packaging method may include indecent images, and the company does not care to whom it sells or how the product is used?

There is no objection to working in an engineering design and projects company and participating in a cosmetics factory project for a foreign company. The fact that the company owning the project might package cosmetics with immodest images, or sell them to those who might use them for impermissible purposes, or be unaware of the materials that will be used in manufacturing cosmetics, does not prevent the establishment of the project. This is because the project is not specifically for the unlawful, nor is it intended for it.
