Sahih Bukhari

These are the small Bangla Collection of Hadith so far.
InshaAllah, it will be updated soon.
A small reminder to the muslim[even to non-muslims] the hadiths or qur'an's meaning is best preserved in the arabic language. The translations do only a little justice to the meanings. But again gathering knowledge is fard fard for us. As Allah[swt] says in qur'an surah Al-Alaq
"Read: In the name of thy Lord who createth, Createth man from a clot. Read: And thy Lord is the Most Bounteous,Who teacheth by the pen, Teacheth man that which he knew not." 96:01-96:05
