This is a basic self-study course of Islam. Islam, the last of the messages of Allah, the Creator, to mankind, is a universal guidance to the human race everywhere, up to the end of time. Islamic teachings are embodied in the Holy Qur'an, the Word of Allah, revealed to the Seal of Messengers, Muhammad (peace be upon him). The Prophet's teachings and life are considered to be a detailed interpretation and a human model for the message. This book features a comprehensive outline of the knowledge essential for every muslim. The outlines are essentially translated summaries of twelve Arabic textbooks. They cover a broad spectrum of Islamic knowledge, grouped in six parts: faith, sources, worship, conduct, law, and prophet's biography.
