বখরমসলমআব দউদতরমজ is an educational app developed by FnF Studio for Android devices. It falls under the category of Education & Reference and specifically focuses on Books. This app is a compilation of the six major Bengali Hadith books, known as সিহাহ সিত্তাহ (Sihah Sittah), which are সহীহুল বুখারী (Sahih Bukhari), সহীহ মুসলিম (Sahih Muslim), সুনানে আবু দাউদ (Sunan Abu Dawood), সুনানে তিরমিজী (Sunan At-Tirmidhi), সুনানে ইবনে মাজাহ (Sunan Ibn Majah), and সুনানে নাসাঈ (Sunan An-Nasai).

The app provides the complete collections of Sahih Bukhari, Sahih Muslim, and the other four Sunan books. If the same Hadith is mentioned in both Sahih Bukhari and Sahih Muslim, it is referred to as "Muttafaqun Alaihi" Hadith. Sahih Bukhari and Sahih Muslim together are known as Sahihain. Apart from Sahihain, there are four more Sunan books included in this app.

বখরমসলমআব দউদতরমজ is a valuable resource for those interested in studying and understanding Bengali Hadith literature.
