The ruling on participating in companies in which riba (usury or interest) has been established

The questioner : He says: Honorable Shaykh, may Allah grant you success. Some colleagues have invested in some joint-stock companies or internal banks that were previously issued a fatwa (scholarly legal ruling) at their establishment stating that they were permissible. It has become clear that they contain obvious riba (usury or interest). When the brothers advised them, they said there is no room for discussion or any side of the discussion, as a fatwa (scholarly legal ruling) was issued by worthy scholars. I ask for clarification. May Allah keep you safe.

The Shaykh : An ordinary person cannot derive rulings from their evidence. Therefore, it is obligatory for him to ask the people of knowledge, as Allah the Exalted said: If it is confirmed that a fatwa (scholarly legal ruling) was issued by trusted scholars, whose knowledge and trustworthiness are relied upon, and who understood the matter in its true reality, and if they issued a fatwa (scholarly legal ruling) that participating in this matter is permissible, then there is no harm in a person participating in it. However, if it becomes clear to a person that participating in this field involves riba (usury or interest), it is not permissible for him to proceed with it, even if people have issued a fatwa (scholarly legal ruling) permitting it. Good, good. Good.
