There are applications on the internet for surveys and polls that pay users for completing them. The question is whether it is permissible to accept money from these applications.
Peace be upon you. It is permissible as long as your work does not involve anything forbidden or promote corruption. This is considered a reward given by the application owner or company for completing a task. May you be successful in all good things.
