The Society of the Revival of Islamic Heritage (Arabic: ﺟﻤﻌﻴﺔ اﺣﻴﺎء اﻟﺘﺮاث اﻻﺳﻼﻣﻲ) (RIHS) is a Kuwait-based NGO with branches in a number of countries.
According to the Spanish intelligence agency CNI, Kuwait provided funding and aid to Islamic associations and congregations in Spain through its subsidiary branch of RIHS.
Kuwait this way funded mosques in Reus and Torredembarra who spread an ideology contrary to the integration of Muslims into Spanish society and fostering hatred of non-Muslims.
[5] The United States has the organization listed on the OFAC SDN list (as Administration of the Revival of Islamic Heritage Society Committee), thus prohibiting U.S. citizens and permanent residents from doing business with the organization.
The continued detention of several Guantanamo captives has been justified, in part, through their association with the Revival of Islamic Heritage Society.
