Fortress of Monotheism (in Bengali language)

For the sake of unifying Allah — عزوجل — and establishing His worship, the creation was created, and to achieve this, every worship was legislated. So, monotheism is the greatest goal, the highest aim, and the noblest purpose. Allah, the Most High, said: (And I did not create the jinn and mankind except to worship Me). And whoever reflects on the state of many today finds that this matter has escaped from their grasp in many aspects. Therefore, it is incumbent upon us to strive to produce such a booklet that includes some of what the scholars have written about monotheism, sincerity of religion to Allah, abandoning innovations, and newly invented matters. The book contains 184 pages, in Bengali language.
