What is the ruling on subscribing to "Ma'aden" company shares?

It is not permissible to contribute to "Ma'aden" company because it deals with interest-based loans and is classified as a "mixed" company, meaning its core business is permissible but it engages in prohibited transactions. This is the view of most contemporary scholars. Sheikh Muhammad bin Saud Al-Osaimi has affirmed the impermissibility of subscribing to it due to its interest-based debt, calling on it to follow Sharia-compliant financing methods and to seek assistance from a Sharia advisor.
