Among the subjects that have not been adequately covered in the English language, perhaps the most important of them is the one covered in the pages of this book. The author presents the belief of Ahl al-Sunnah wal-Jama’ah, which is the creed of the first few generations of Muslims and those who followed in their footsteps. Besides outlining the principles and foundations of this creed he also highlights some of the foreign ideas and deviant concepts that have crept into the hearts and minds. The style in which this book has been written relates more to a textbook than to a book for casual reading. The author has carefully structured the book, divided it into clearly headed sections and provided all the necessary definitions and explanations that will facilitate a clear understanding of this immensely important branch of knowledge.
