Is it permissible to establish an interactive voice response (IVR) project that allows customers to obtain information or services (such as car and apartment offers, listening to songs, and participating in competitions) for an additional fee on the call, with the consumer's knowledge?

There is no objection to undertaking this project, as long as its operation does not entail any Sharia-prohibited aspects. This is conditional on its use for what is permissible by Sharia, such as a service for displaying cars or promoting sales. However, its use for what is forbidden by Sharia is not permissible, such as listening to music. It is permissible to use it for participating in competitions if they adhere to Sharia guidelines.
