The Quran and Hadith are two primary sources of Islamic guidance and knowledge. The Quran is the holy book of Islam and is considered to be the direct word of Allah as revealed to the Prophet Muhammad (peace be upon him) through the Angel Gabriel. The Hadith, on the other hand, refers to the collection of sayings and actions of the Prophet Muhammad (peace be upon him) that were recorded by his companions and later compiled into various books.

Bangla Quran refers to the translation of the Quran into the Bengali language, which is spoken primarily in Bangladesh and parts of India. There are several translations of the Quran into Bengali, including those by Muhiuddin Khan, Moududi, and Yusuf Ali.

Similarly, there are several collections of Hadith in Bengali, including the Sahih Bukhari, Sahih Muslim, and Sunan Abu Dawood. These collections have been translated into Bengali by various scholars and are widely used by Bengali-speaking Muslims for guidance and knowledge.

In summary, the Bangla Quran and Hadith are important sources of Islamic knowledge and guidance for Bengali-speaking Muslims, and there are various translations and collections available in the Bengali language.
