Investment is one of the muamalah activities that aims to increase the value of assets owned at this time which will be used for future interests. As a country that has the most Muslim population in the world the Indonesian government has seriously worked on a system where Muslim communities can invest comfortably, but this is contrary to the facts in the field. The level of inclusion of Islamic investment products is still very low, and the managed funds of Indonesian Sharia investments are still far behind Malaysia and Saudi Arabia, which have fewer Muslim populations than Indonesia. In view of this, the potential use of Sharia investment in increasing its market share is still large and wide open considering that the Muslim population in Indonesia is the largest in the world. There are many factors that influence the use of a product, especially investment. This study aims to determine whether the level of community religiosity and the level of Islamic financial literacy influence the use of Islamic investment products.
