God declares in the Quran, ?The only religion in the sight of Allah is Islam,? and that ?if anyone desires a religion other than Islam, it will not be accepted from him: Therefore, seeking knowledge about Islam is the inviolable, sacrosanct duty of all human beings. It is binding upon all to familiarize themselves with the tenets of Islam, which Allah declares in His infallible Book, the Quran, to be the religion which he has chosen for mankind. Ignorance about its indubitable words of wisdom and human salvation does not give anyone the license to deny this religion of Allah. Indeed, such ignorance an inexcusable moral condition. This book presents the foremost principles of Islam in a very comprehensible, reader-friendly, lucid, and concise manner. The purpose of the book is to provide its readers with full details about articles of faith, the pillars of Islam and general rules encompassing all prohibitions pertaining to food and drink, clothes, professions, matters of family relations, etc. in a very clear and conclusive manner, which is in consonance with the teachings of the Quran. Islam represents Divine religion, which is free from ambiguity and dissonance. This book aims at building faith in precisely this manner. It is a work par excellence, which teaches in the simplest and most pellucid fashion the tenets which are the building blocks of Islam. The ineffable beauty of this book is the brevity of its language and the precision of its teachings.
