as-Sirat al-Mustaqim by al-Muhaddith ^Abdullah al-Harariyy.
In a time of pervasive ignorance that spreads like wildfire, and a time in which supposed Muslims do not even understand basic matters of the religion (some even becoming full-fledged apostates), we are highly fortunate to have the likes of Sheikh ^Abdullah al-Harariyy in our midst. He is an individual who has spent most of his life warning against the deviations that have plagued this nation, and who has upheld the truth at whatever cost. Through him, thousands - rather, hundreds of thousands of people have been guided to knowing the essential rules and beliefs of the Islamic religion, and therefore to safety from the various types of blasphemy that are commonly fallen into.
This book, as-Sirat al-Mustaqim, is truly a masterpiece. It is primarily focused around explaining the creed of Islam, and refuting, step by step, each erroneous misconception that so many people in the modern era have fallen victim to. It is a highly elaborate book, rich and intricate in details, and embellished with quotations and proofs. After reading a section, one can't help but feel a great sense of satiety; all that one wished to know about the topic is expounded upon, and more.
I highly recommend this book to all modern students of Islamic knowledge.
NB The correct way to take any knowledge of the religion is by learning it directly from somebody with a chain (Isnad), and not simply by self-reading.
