Hisn Al-Muslim is a comprehensive and user-friendly application that provides a full explanation of Islamic invocations, or dhikrs, along with audio services, making it easy for you to read, listen, and understand all in one. The app is available in 20 different languages and features a user-friendly interface, along with many other useful features. It is the only certified application by Sheikh Sa`id Ibn `Ali Al-Qahtani (may Allah have mercy upon him). The app offers a detailed explanation for each dhikr, including wording, vocabularies, and lessons derived from the hadith, and attributes every hadith to its original source. You can listen to the dhikrs by Hamad Ibn Muhammad A-Durayhim’s performance, count the number of tasbih and istighfar you perform, and customize view settings through changing font color, size and type. You can also record your own personal dhikrs in the application, collect your favorite dhikrs in one place, and activate night mode for better experience in dark and low-light environments.
