Languages of Bangladesh
Arabic (عربي) was an official language ever since the territory of the modern state People's Republic of Bangladesh became a part of the Bengal Sultanate. However some disagree and believe the presence of Arabic came before during the Delhi Sultanate. Arabic is used in many Muslim congregations such as the weekly Jumu'ah Salah in which a sermon (khutbah) is given in Arabic in addition to Bengali. In the Constitution of Bangladesh, there are two references to Arabic to in the introduction and Part I of the constitution. The document begins with the Arabic phrase بِسْمِ اللهِ الرَّحْمٰنِ الرَّحِيْمِ which is translated as “In the name of Allah, the Beneficent, the Merciful”. Article 2A declares that Islam is the state religion of the republic.
