"Towards the end of his rule, Mujib made frequent references to Islam in his speeches and public utterances by using terms and idioms which were peculiar mainly to the Islam-oriented Bangladeshi— like Allah (the Almighty God), Insha Allah (God willing), Bismillah (in the name of God), Tawaba (Penitence) and Imam (religious leader). As days passed on Shiekh Mujib even dropped his symbolic valedictory expression Joy Bangla (Glory to Bengal) and ended his speeches with Khuda Hafez (May God protect you), the traditional Indo-Islamic phrase for bidding farewell. In his later day speeches, he also highlighted his efforts to establish cordial relations with the Muslim countries in the Middle East."
