Hadza is an Android application developed by Ahmad Tholhah Maruf. It falls under the category of Education & Reference, specifically in the Books subcategory. This app aims to provide users with a collection of Salaf books as religious references.

In addition to serving as a religious reference, Hadza also offers various prayers (wirid) to be recited in specific cycles, such as the Quran, Sholawat Dalailul Khoirot, Hizib, and more. The app can be used both online and offline, allowing users to download and access the books even without an internet connection.

Although the app may not have as extensive a list of books as similar applications, Hadza promises continuous development in the future. With its user-friendly interface and comprehensive collection of Islamic books and prayers, Hadza is a valuable resource for individuals seeking religious guidance and knowledge.
